Subject: Input: gpio_mouse - add device tree probing
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=adb77b3e5118d2760621d8cc740524b816f9006b;p=linux.git

Input: gpio_mouse - add device tree probing

This makes the GPIO mouse probe nicely from the device tree if found in a
tree. As the driver uses device properties it can easily be amended to also
probe from ACPI devices.
