    drm: Update drm_irq.c...
    
    ... to commit 56cc279b29c7b204fe7d0943509ae209b8b128db from Linux 3.18
    drm: Fix deadlock between event_lock and vbl_lock/vblank_time_lock
    
    Imre VadÃ¡sz noticed a deadlock in the drm code handling vblank irqs.
    Fortunately, this was also noticed by the Linux drm developers and fixing
    the issue was just a matter of updating drm_irq.c
