Subject: drm/i915/dp: Use connector DSC DPCD in i915_dsc_fec_support_show()
X-Git-Tag: v6.7-rc1~145^2~9^2~18
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=102c8013b6536d93506d85d6664968e51556102c;p=thirdparty%2Fkernel%2Flinux.git

drm/i915/dp: Use connector DSC DPCD in i915_dsc_fec_support_show()

Use the connector's DSC DPCD capabilities in i915_dsc_fec_support_show()
instead of the version stored in the encoder. Atm the two are identical,
but a follow-up patch will store the (MST) connector specific version
in the connector.
