[Intel-gfx] [PATCH 2/2] drm/i915: replace for_each_engine()
Dave Gordon
david.s.gordon at intel.com
Wed Mar 23 18:19:54 UTC 2016
Having provided for_each_engine_id() for cases where the third (id)
argument is useful, we can now replace all the remaining instances with
a simpler version that takes only two parameters. In many cases, this
also allows the elimination of the local variable used in the iterator
(usually 'i').
