patch "iio: hid-sensor-als: Return 0 for HID_USAGE_SENSOR_TIME_TIMESTAMP" added to char-misc-linus

[<gregkh@linuxfoundation.org>]

This is a note to let you know that I've just added the patch titled

    iio: hid-sensor-als: Return 0 for HID_USAGE_SENSOR_TIME_TIMESTAMP

to my char-misc git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: iio: hid-sensor-als: Return 0 for HID_USAGE_SENSOR_TIME_TIMESTAMP

When als_capture_sample() is called with usage ID
HID_USAGE_SENSOR_TIME_TIMESTAMP, return 0. The HID sensor core ignores
the return value for capture_sample() callback, so return value doesn't
make difference. But correct the return value to return success instead
of -EINVAL.
