Subject: drm/amd/display: drop ASSERT() if eDP panel is not connected
X-Git-Tag: v5.3-rc2~20^2^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=58caae27df41d2ef3b1ae3bd06284da5b85ac288;p=thirdparty%2Flinux.git

drm/amd/display: drop ASSERT() if eDP panel is not connected

[Why]
For boards that support eDP but do not have a physical eDP
display connected an ASSERT will be thrown. This is not a
critical failure and shouldn't be treated as such.

[How]
Drop the assertion.
