Subject: [PATCH 01/56] kdrive: set "evdev" driver for input devices
 automatically, if available.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If kdrive input driver "evdev" is available, no other driver was
explicitly set for a given input device, and its kernel device node is
/dev/input/event*, this patch will make kdrive set "evdev" driver
automatically for such device.
