[PATCH] HID: magicmouse: do not set up autorepeat

[Dmitry Torokhov]

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).

Jiri, Benjamin, this is fixes jitter in event packets that became
apparent when we moved the point at which timestamps are being
generated, so maybe mark for stable?

Thanks!

I've marked it for stable, fixed the typo in the comment, and applied, 
thanks.
