[PATCH 02/12] drm/i915: Remove redundant initialisation of per-ring IRQ waitqueues

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The waitqueues are already initialised during ring initialisation so
kill the redundant and duplicated code to do so in each generations IRQ
installer.
