Subject: mtd: mtdblock: Use DEFINE_MUTEX() for mtdblks_lock
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7578ca927b1a2a0445c9a3166d05462b9ffd4c06;p=linux-beck.git

mtd: mtdblock: Use DEFINE_MUTEX() for mtdblks_lock

mtdblks_lock can be initialized automatically with
DEFINE_MUTEX() rather than explicitly calling mutex_init().
