[igt-dev] [PATCH v4 1/1] i915_pm_rpm: remove gem-execbuf-stress-extra-wait because same as gem-execbuf-stress

[Caz Yokoyama]

Extra 5sec delay does not add any value more than gem-execbuf-stress.
It waits until suspend state after a job is added by gem_execbuf().
There is no need to do more when GPU becomes suspended state.
I confirm this by looking at pm_runtime_force_suspend() which exits
on suspend state.
