[PATCH 2/4] drm/i915: Don't init hpd polling for vlv and chv from runtime_suspend()

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

 



An error in the condition for avoiding the call to intel_hpd_poll_init()
for valleyview and cherryview from intel_runtime_suspend() caused it to
be called unconditionally. Fix it.

Found by coverity.
