[Intel-gfx] [PATCH] drm/i915/dp: Clean up/Get rid of detect_done flag

[Manasi Navare]

Detect_done flag was added previously when intel_dp_long_pulse
was called from multiple places. However now it is called only
from intel_dp_detect(). So this flag becomes redundant.
Anyway now, we set this to false right away after intel_dp_long_pulse
so it calls long pulse handler always for all calls to .detect()
