Subject: [PATCH v2 03/11] drm/i915/dp_mst: Fix BW limit check when calculating DSC DPT bpp
Date: Wed, 17 Apr 2024 01:10:02 +0300	[thread overview]
Message-ID: <20240416221010.376865-4-imre.deak@intel.com> (raw)
In-Reply-To: <20240416221010.376865-1-imre.deak@intel.com>

The DSC DPT bpp limit check should only fail if the available DPT BW is
less than the required BW, fix the check accordingly.
