[PATCH resend] hid-magicmouse: Increase evdev buffer size

From: Chase Douglas
Date: Fri Apr 01 2011 - 17:03:48 EST


The evdev buffer isn't big enough when you get many fingers on the
device. Bump up the buffer to a reasonable size, matching what other
multitouch devices use. Without this change, events may be discarded in
the evdev buffer before they are read.
