From: Jani Nikula Date: Wed, 20 Sep 2023 11:29:01 +0000 (+0300) Subject: drm/i915: add a note about fec_enable with 128b/132b X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7e1ca09667128c661c03aced310d59b99db13bb7;p=linux.git drm/i915: add a note about fec_enable with 128b/132b Add a note that fec_enable actually means FEC is to be enabled explicitly. 128b/132b always has FEC enabled, the driver doesn't need to enable it separately, and fec_enable will be false.
