HID: magicmouse: Do not set BTN_MOUSE on double report
Under certain conditions the Magic Trackpad can group 2 reports in a
single packet. The packet is split and the raw event function is
invoked recursively for each part.
However, after processing each part, the BTN_MOUSE status is updated,
sending multiple click events. [1]
Return after processing double reports to avoid this issue.
