2017-06-05platform/x86: acer-wmi: setup accelerometer when machine has appropriate ↵Lee, Chun-Yi1-4/+18
notify event commit 98d610c3739ac354319a6590b915f4624d9151e6 upstream. The accelerometer event relies on the ACERWMID_EVENT_GUID notify. So, this patch changes the codes to setup accelerometer input device when detected ACERWMID_EVENT_GUID. It avoids that the accel input device created on every Acer machines. In addition, patch adds a clearly parsing logic of accelerometer hid to acer_wmi_get_handle_cb callback function. It is positive matching the "SENR" name with "BST0001" device to avoid non-supported hardware.

2017-06-05goldfish: Sanitize the broken interrupt handlerThomas Gleixner1-5/+8
commit 6cf18e6927c0b224f972e3042fb85770d63cb9f8 upstream. This interrupt handler is broken in several ways: - It loops forever when the op code is not decodeable - It never returns IRQ_HANDLED because the only way to exit the loop returns IRQ_NONE unconditionally. The whole concept of this is broken. Creating devices in an interrupt handler is beyond any point of sanity. Make it at least behave halfways sane so accidental users do not have to deal with a hard to debug lockup.

commit 4b200b4604bec3388426159f1656109d19fadf6e upstream. This fixes a several year old regression that I found while trying to get the Yoga 3 11 to work. The ideapad_rfk_set function is meant to send a command to the embedded controller through ACPI, but as of c1f73658ed, it sends the index of the rfkill device instead of the command, and ignores the opcode field. This changes it back to the original behavior, which indeed flips the rfkill state as seen in the debugfs interface.

2015-05-06apple-gmux: lock iGP IO to protect from vgaarb changesBruno Prémont1-1/+47
commit 4eebd5a4e72697aac25a8a57d3f888a9d5f80370 upstream. As GMUX depends on IO for iGP to be enabled and active, lock the IO at vgaarb level. This should prevent GPU driver for dGPU to disable IO for iGP while it tries to own legacy VGA IO. This fixes usage of backlight control combined with closed nvidia driver on some Apple dual-GPU (intel/nvidia) systems. On those systems loading nvidia driver disables intel IO decoding, disabling the gmux backlight controls as a side effect. Prior to commits moving boot_vga from (optional) efifb to less optional vgaarb this mis-behavior could be avoided by using right kernel config (efifb enabled but vgaarb disabled). This patch explicitly does not try to trigger vgaarb changes in order to avoid confusing already running graphics drivers. If IO has been mis-configured by vgaarb gmux will thus fail to probe. It is expected to load/probe gmux prior to graphics drivers.

2015-05-04compal-laptop: Check return value of power_supply_registerKrzysztof Kozlowski1-1/+3
commit 1915a718b1872edffcb13e5436a9f7302d3d36f0 upstream. The return value of power_supply_register() call was not checked and even on error probe() function returned 0. If registering failed then during unbind the driver tried to unregister power supply which was not actually registered. This could lead to memory corruption because power_supply_unregister() unconditionally cleans up given power supply. Fix this by checking return status of power_supply_register() call. In case of failure, clean up sysfs entries and fail the probe.

2015-03-02ideapad-laptop: Change Lenovo Yoga 2 series rfkill handlingHans de Goede1-14/+27
commit ce363c2bcb2303e7fad3a79398db739c6995141b upstream. It seems that the same problems which lead to adding an rfkill blacklist and putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13 and Lenovo Yoga 2 Pro too: https://bugzilla.redhat.com/show_bug.cgi?id=1021036 https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612 Testing has shown that the firmware rfkill settings are persistent over reboots. So blacklisting the driver is not good enough, if the wifi is blocked at the firmware level the wifi needs to be explictly unblocked through the ideapad-laptop interface. And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices with hardware kill switch reports the hardware switch state, needs to be explictly set to 1 (radio enabled / not blocked). So this patch does 3 things to get proper rfkill handling on these models: 1) Instead of blacklisting the rfkill functionality, which means that people with a firmware blocked wifi get stuck in that situation, ignore the value reported by the not present hardware rfkill switch, as this is what is causing ideapad-laptop to wrongly report all radios as hardware blocks. But do register the rfkill interfaces so that the user can soft [un]block them. 2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1 3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2 series is affected.

2015-02-24samsung-laptop: Add use_native_backlight quirk, and enable it on some modelsHans de Goede1-3/+17
commit 4690555e13c48fef07f2762f6b0cd6b181e326d0 upstream. Since kernel 3.14 the backlight control has been broken on various Samsung Atom based netbooks. This has been bisected and this problem happens since commit b35684b8fa94 ("drm/i915: do full backlight setup at enable time") This has been reported and discussed in detail here: http://lists.freedesktop.org/archives/intel-gfx/2014-July/049395.html Unfortunately no-one has been able to fix this. This only affects Samsung Atom netbooks, and the Linux kernel and the BIOS of those laptops have never worked well together. All affected laptops already have a quirk to avoid using the standard acpi-video interface and instead use the samsung specific SABI interface which samsung-laptop uses. It seems that recent fixes to the i915 driver have also broken backlight control through the SABI interface. The intel_backlight driver OTOH works fine, and also allows for finer grained backlight control. So add a new use_native_backlight quirk, and replace the broken_acpi_video quirk with this quirk for affected models. This new quirk disables acpi-video as before and also stops samsung-laptop from registering the SABI based samsung_laptop backlight interface, leaving only the working intel_backlight interface. This commit enables this new quirk for 3 models which are known to be affected, chances are that it needs to be used on other models too.

2015-01-15platform/chrome: chromeos_laptop - Add support for Acer C720Mika Westerberg1-6/+39
commit da3b0ab75aadab63d1ffd5563100c9386e444dad upstream. Acer C720 has touchpad and light sensor connected to a separate I2C buses. Since the designware I2C host controller driver has two instances on this particular machine we need a way to match the correct instance. Add support for this and then register both C720 touchpad and light sensor.

2014-11-14acer-wmi: Add acpi_backlight=video quirk for the Acer KAV80Hans de Goede1-0/+11
commit 183fd8fcd7f8afb7ac5ec68f83194872f9fecc84 upstream. The acpi-video backlight interface on the Acer KAV80 is broken, and worse it causes the entire machine to slow down significantly after a suspend/resume. Blacklist it, and use the acer-wmi backlight interface instead. Note that the KAV80 is somewhat unique in that it is the only Acer model where we fall back to acer-wmi after blacklisting, rather then using the native (e.g. intel) backlight driver. This is done because there is no native backlight interface on this model.

2014-06-11hp-wmi: Enable hotkeys on some systemsKyle Evans1-0/+18
This is a third attempt to enable these buttons. The new variable being commit 997daa1bd9aca412ab97955a35b26c460c0ec7a4 (i.e. hp-wmi: detect "2009 BIOS or later"). Older systems that do not have the 2009 BIOS query method respond with a dummy value, in this case 4. Using that, we can target a fairly narrow group of systems. i.e. old enough to not have HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9. This group may be further limited if some systems respond with something other than 4 to non-existant feature queries.

2014-06-11thinkpad_acpi: Add mappings for F9 - F12 hotkeys on X240 / T440 / T540Hans de Goede1-1/+3
The T440s user guide says that when Fn-lock is not active, the *40s' F9 - F12 keys should be mapped to: control-panel, search, show-all-windows and Computer. These keys generate the sofar unused 28 - 31 hotkey scancodes. For the first 2 this nicely matches the icons on the keys, for the latter 2 the icons are somewhat creative, which is why I ended up looking them up in the user manual.

2014-06-11ideapad_laptop: Introduce the use of the managed version of kzallocHimangi Saraogi1-5/+3
This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions. The label sysfs_failed is removed as it is no longer required. Also, linux/device.h is added to make sure the devm_*() routine declarations are unambiguously available. The following Coccinelle semantic patch was used for making the change: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
