[PATCH 1/4] max3110: wake up fixes

[Alan Cox <alan@lxorguk.ukuu.org.uk>]

From: Dirk Brandewie <dirk.brandewie@gmail.com>

The main thread is waiting on on a wait_queue but wake_up_process() is
used to wake the thread. This reads weirdly. Change wake_up_process() to
wake_up().

Tested on the Moorestown tablet build
