Subject: [Intel-gfx] [PATCH 2/2] drm/i915/dp_mst: Clear ACT sent flag before waiting for it
Date: Wed, 10 Jun 2020 21:31:32 +0300	[thread overview]
Message-ID: <20200610183132.13341-2-imre.deak@intel.com> (raw)
In-Reply-To: <20200610183132.13341-1-imre.deak@intel.com>

We do this during enabling, but not during disabling. BSpec doesn't
require this explicitly in either case, however based on my tests
nothing clears it after it gets set, so let's do this during disabling
as well.
