Subject: HID: hid-magicmouse: Increase evdev buffer size
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cc5e0f08ca2a66fc4c6984ccff74fd529e969fac;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

HID: hid-magicmouse: Increase evdev buffer size

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.
