Subject: [PATCH 4.14 094/125] HID: magicmouse: do not set up autorepeat

From: Dmitry Torokhov <dmitry.torokhov@...il.com>

commit 6363d2065cd399cf9d6dc9d08c437f8658831100 upstream.

Neither the trackpad, nor the mouse want input core to generate autorepeat
events for their buttons, so let's reset the bit (as hid-input sets it for
these devices based on the usage vendor code).
