Subject: mmc_test: initialize mmc_test_lock statically
From: Akinobu Mita <akinobu.mita@xxxxxxxxx>
The mutex mmc_test_lock is initialized at every time mmc_test device is
probed. Probing another mmc_test device may break the mutex, if the probe
function is called while the mutex is locked.
This patch fixes it by statically initializing mmc_test_lock.
