[PATCH] drm/i915: Lock timeline mutex directly in error path of eb_pin_timeline

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

 



Don't use the interruptable version of the timeline mutex lock in the
error path of eb_pin_timeline as the cleanup must always happen.

v2:
 (John Harrison)
  - Don't check for interrupt during mutex lock
