Subject: Use __SPIN_LOCK_UNLOCKED to initialize bad_irq_desc.lock
X-Git-Tag: firefly_0821_release~15666^2~4
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6fd7ad96d6c51ba15479cb74dcb189b666422394;p=firefly-linux-kernel-4.4.55.git

Use __SPIN_LOCK_UNLOCKED to initialize bad_irq_desc.lock

SPIN_LOCK_UNLOCKED is deprecated as lockdep cannot properly work with
locks initialized with it.

This fix is necessary to compile the linux-rt tree for ARM.
