From a650031a6bd16cb6789da9b3c27fc97341239f12 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Sat, 13 Sep 2008 19:03:32 +0900 Subject: 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.
