Subject: Input: uvc - the button on the camera is KEY_CAMERA
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=74ca11c2056d01d9ebb3615cd781a148450c3c82;p=linux-2.6-omap-h63xx.git

Input: uvc - the button on the camera is KEY_CAMERA

Cameras should generate KEY_CAMERA, not BTN_0. Also call input_sync()
on the device once the button has been pressed.
