[PATCH 2/6] mfd: max8925: fix mfd device register failure

From: Haojian Zhuang
Date: Mon Feb 04 2013 - 10:42:16 EST


From: Qing Xu <qingx@xxxxxxxxxxx>

we encounter rtc/power/touch driver registry failure, root cause
it is resources confilict in insert_resouce, solved by changing
mfd_add_devices 5th parameter to NULL
