Subject: drm/amd/display: Fix construct_phy with MXM connector
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=ec9e2e7acc6dabb8f00c2c60785931310caaa883;p=users%2Fjedix%2Flinux-maple.git

drm/amd/display: Fix construct_phy with MXM connector

[Why/How]
The call to construct_phy will fail in cases where connector type is
MXM, and the dc_link won't be properly created/initialized.
