2015-08-19HID: usbhid: Fix the check for HID_RESET_PENDING in hid_io_errorDon Zickus1-1/+1
It was reported that after 10-20 reboots, a usb keyboard plugged into a docking station would not work unless it was replugged in. Using usbmon, it turns out the interrupt URBs were streaming with callback errors of -71 for some reason. The hid-core.c::hid_io_error was supposed to retry and then reset, but the reset wasn't really happening. The check for HID_NO_BANDWIDTH was inverted. Fix was simple. Tested by reporter and locally by me by unplugging a keyboard halfway until I could recreate a stream of errors but no disconnect.

2015-08-11HID: wacom: Report correct device resolution when using the wireless adapaterJason Gerecke1-33/+37
The 'wacom_wireless_work' function does not recalculate the tablet's resolution, causing the value contained in the 'features' struct to always be reported to userspace. This value is valid only for the pen interface, meaning that the value will be incorrect for the touchpad (if present). This in particular causes problems for libinput which relies on the reported resolution being correct. This patch adds the necessary calls to recalculate the resolution for each interface. This requires a little bit of code shuffling since both the 'wacom_set_default_phy' and 'wacom_calculate_res' are declared below their new first point of use in 'wacom_wireless_work'.

2015-08-10HID: wacom: Do not repeatedly attempt to set device mode on errorJason Gerecke1-1/+1
As an extension of aef3156d7, there is no sense in repeatedly calling the 'wacom_set_report' and 'wacom_get_report' functions if they return an error. Getting an error from them implies that the device is out to lunch: either a hard error code was returned or repeated attempts at recovering from a "soft" error all failed. In either case, doing even more retries is not likely to resolve whatever is wrong. Signed-off-by: Jason Gerecke <jason.gerecke@wacom.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2015-08-04HID: hid-input: Fix accessing freed memory during device disconnectKrzysztof Kozlowski1-2/+5
During unbinding the driver was dereferencing a pointer to memory already freed by power_supply_unregister(). Driver was freeing its internal description of battery through pointers stored in power_supply structure. However, because the core owns the power supply instance, after calling power_supply_unregister() this memory is freed and the driver cannot access these members. Fix this by storing the pointer to internal description of battery in a local variable before calling power_supply_unregister(), so the pointer remains valid.

Instead of having a single 'input_dev' device that will take either pen or touch data depending on the type of the device, create seperate devices devices for each.

2015-06-18HID: wacom: Introduce a new WACOM_DEVICETYPE_PAD device_typeJason Gerecke3-64/+73
Historically, both the touch and pad tools would have shared the 'BTN_TOOL_FINGER' type. Any time you needed to distinguish the two, you had to use some other bit of knowledge (e.g. that the pad was on the same interface as the pen, and thus 'touch_max' would be zero). To make these checks more readable, we introduce WACOM_DEVICETYPE_PAD. Although we still have to rely on other bits of knowledge to set this bit on the right interface (since it cannot be detected from the HID descriptor), it can be done just once inside 'wacom_setup_device_quirks'.

2015-06-18HID: wacom: Treat features->device_type values as flagsJason Gerecke3-32/+38
The USB devices that this driver has historically supported segregate the pen and touch portions of the tablet. Oftentimes the segregation would be done at the interface level, though on occasion (e.g. Cintiq 24HDT) the tablet would combine two totally independent USB devices behind an internal USB hub. Because pen and touch never shared the same interface, it made sense for the 'device_type' to store a single value: "pen" or "touch". Recently, however, some I2C devices have been created which combine the two. A first step to accomodating this is to expand 'device_type' so that it can represent two (or potentially more) types simultaneously. To do this, we treat it as a bitfield and set/check individual bits rather than using the '=' and '==' operators. This should not result in any functional change since no supported devices (that I'm aware of, at least) have HID descriptors that indicate both pen and touch reports on a single interface.

2015-06-01HID: hidpp: Add driver for mouse logitech M560Goffredo Baroncelli1-3/+224
The Logitech M560 is a wireless mouse designed for windows 8 which uses the unifying receiver. Compared to a standard one, some buttons (the middle one and the two ones placed on the side) are bound to a key combination instead of a generating classic "mouse" button events. The device shows up as a mouse and keyboard combination: when the middle button is pressed it sends a key (as keyboard) combination, the same happens for the two side button. The left/right/wheel work as expected from a mouse. To complicate things further, the middle button sends different keys combinations between odd and even presses. In the "even" press it also sends a left click. But the worst thing is that no event is generated when the middle button is released. It is possible to re-configure the mouse sending a command (see function m560_send_config_command()). After this command the mouse sends some useful data when the buttons are pressed and/or released.

2015-05-21HID: wacom: Have wacom_{get,set}_report retry on -EAGAIN, not -EPIPEJason Gerecke1-2/+10
Retrying on -EPIPE makes very little sense since this typically indicates a problem that will not just disappear on its own. For instance, the USB documentation states that it will be sent if the endpoint is stalled or the device has disconnected. Instead, we should retry if -EAGAIN is received since this indicates a temporary error condition such as a busy bus. In addition to adjusting the conditions we retry under, we also log an error on failure so that we can be aware of what's going on.

We assumed all touch interfaces report touch data. But, Bamboo and Intuos non-touch devices report express keys on touch interface. We need to check touch_max before counting touches.

2015-05-18HID: i2c-hid: fix harmless test_bit() issueDan Carpenter1-3/+3
These defines are used like this: if (test_bit(I2C_HID_STARTED, &ihid->flags)) The intent was to use bits 0, 1, and 2 but because of the extra shifts we're using bits 1, 2, and 4. It's harmless becuase it's done consistently but it's not the intent and static checkers will complain.
