Re: [PATCH v3 02/10] mtd: powernv_flash: Lock around concurrent access to OPAL

OPAL can only manage one flash access at a time and will return an
OPAL_BUSY error for each concurrent access to the flash. The simplest
way to prevent this from happening is with a mutex.

Should the mutex_lock() be mutex_lock_interruptible()? Are we OK waiting on
the mutex while other operations with the lock are busy?
