Subject: [PATCH 07/16] drm/i915/dp: Fix BW check in is_bw_sufficient_for_dsc_config()
Date: Mon, 15 Dec 2025 21:23:47 +0200 [thread overview]
Message-ID: <20251215192357.172201-8-imre.deak@intel.com> (raw)
In-Reply-To: <20251215192357.172201-1-imre.deak@intel.com>
is_bw_sufficient_for_dsc_config() should return true if the required BW
equals the available BW, make it so.
