Subject: drm/amd/display: Initialize dsc_caps to 0
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=d18ecfee5187e3b2dbff7e67dda8b2f54ff5231c;p=thirdparty%2Flinux.git

drm/amd/display: Initialize dsc_caps to 0

[Why&How]
If we don't do that we make DSC decisions based on random
inputs, which might result in disallowing DSC when the
monitor and HW support it.
