Subject: [PATCH] cs5535 mfgpt - fix wrong if condition

From: Christian Gmeiner <christian.gmeiner@...il.com>

This patch fixes the wrong if condition for the check if the
requested timer is available.

The bitmap avail is used to store if a timer is used already.
test_bit() is used to check if the requested timer is
available. If a bit in the avail bitmap is set it means that the
timer is available.
