devm_clk_get allocates a resource that is released when a driver detaches.
This patch uses devm_clk_get for data that is allocated in the probe
function of a platform device and is only released in the remove function.

This patch supports exynos's emulation mode with newly created sysfs node.
Exynos 4x12 (4212, 4412) and 5 series provide emulation mode for thermal
management unit. Thermal emulation mode supports software debug for TMU's
operation. User can set temperature manually with software code and TMU
will read current temperature from user value not from sensor's value.
This patch includes also documentary placed under Documentation/thermal/.

leds: leds-gpio: set devm_gpio_request_one() flags param correctly
|
|
commit a99d76f leds: leds-gpio: use gpio_request_one
changed the leds-gpio driver to use gpio_request_one() instead
of gpio_request() + gpio_direction_output()
Unfortunately, it also made a semantic change that breaks the
leds-gpio driver.
The gpio_request_one() flags parameter was set to:
GPIOF_DIR_OUT | (led_dat->active_low ^ state)
Since GPIOF_DIR_OUT is 0, the final flags value will just be the
XOR'ed value of led_dat->active_low and state.
This value were used to distinguish between HIGH/LOW output initial
level and call gpio_direction_output() accordingly.
With this new semantic gpio_request_one() will take the flags value
of 1 as a configuration of input direction (GPIOF_DIR_IN) and will
call gpio_direction_input() instead of gpio_direction_output().
int gpio_request_one(unsigned gpio, unsigned long flags, const char *label)
{
..
if (flags & GPIOF_DIR_IN)
err = gpio_direction_input(gpio);
else
err = gpio_direction_output(gpio,
(flags & GPIOF_INIT_HIGH) ? 1 : 0);
..
}
The right semantic is to evaluate led_dat->active_low ^ state and
set the output initial level explicitly.

The socket calls from vxlan to join/leave multicast group aren't
using the index of the underlying device, as a result the stack uses
the first interface that is up. This results in vxlan being non functional
over a device which isn't the 1st to be up.
Fix this by providing the iflink field to the vxlan instance
to the multicast calls.

Ulrich reported that his USB3 cardreader does not work reliably when
connected to the USB3 port. It turns out that USB3 controller failed to
awaken when plugging in the USB3 cardreader. Further experiments found
that the USB3 host controller can only be awakened via polling, not via PME
interrupt. But if the PCIe port to which the USB3 host controller is
connected is suspended, we cannot poll the controller because its config
space is not accessible when the PCIe port is in a low power state.
To solve the issue, the PCIe port will not be suspended if any subordinate
device needs PME polling.

If we request "num_vfs" and the driver's sriov_configure() method enables
exactly that number ("num_vfs_enabled"), we complain "Invalid value for
number of VFs to enable" and return an error. We should silently return
success instead.
Also, use kstrtou16() since numVFs is defined to be a 16-bit field and
rework to simplify control flow.

The function at91_dt_node_to_map is ultimately called by the function
pinctrl_get, which is an exported function. Since it is possible that this
function is not called from within a probe function, for safety, the kfree
is converted to a devm_kfree, to both free the data and remove it from the
device in a failure situation.

3 is an invalid value for the CAN1_IPP_IND_CANRX_SELECT_INPUT
register. Set it to 2, which correctly selects the GPIO_8 pad.

Pull i2c __dev* attribute removal from Wolfram Sang:
"The squashed patches from Bill to get rid of the __dev* annotations in
the i2c subsystem. I couldn't include it in my previous pull request
due to some dependency with the mfd subsystem. I had this patch in
linux-next for two days before rc1 and nothing popped up."

controls API failures"
Commit f0ed2ce840b3 ("[media] uvcvideo: Set error_idx properly for
extended controls API failures") causes user space to behave incorrectly
on one of my test machines (there is no sound under KDE 4.9.4 using
pulseaudio and there is a knotify4 process occupying one of the CPU
cores 100% of the time). Reverting that commit entirely fixes the
problem for me.
However, commit f0ed2ce840b3 appears to do more than it follows from its
changelog, because the changelog only says about the changes related to
ctrls->error_idx, while the commit additionally changes error codes
returned by various functions in uvc_ctrl.c and uvc_v4l2.c. It turns
out that the changes of the returned error codes confuse the user spce,
so it is sufficient to revert the part of commit f0ed2ce840b3 not
mentioned in its changelog to fix the problem.
[ 'ENOENT' is not a valid error return from an ioctl to begin with, and
I don't understand how anybody ever even thought it would be. - Linus ]
