mmc_test: initialize mmc_test_lock statically
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. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
