Subject: [Intel-gfx] [PATCH] drm/i915: Fix the i915_dsc_fec_support debugfs file for DP MST connectors
Date: Tue,  9 Jun 2020 21:41:40 +0300	[thread overview]
Message-ID: <20200609184140.4937-1-imre.deak@intel.com> (raw)
In-Reply-To: <20200608182650.13642-1-imre.deak@intel.com>

DSC is not supported on DP MST streams so just don't add this entry for
MST connectors.

This also fixes an OOPS, caused by the encoder->digport cast, which is
not valid for MST encoders.

v2:
- Check encoder, which is unset for an MST connector, before it gets
  enabled.
v3:
- Just don't add this debugfs file for MST connectors. (Ville)
