[PATCH] drm/amd/display: Remove redundant DRM device struct in amdgpu_dm_, mst_types.c

[Srinivasan Shanmugam]

Declaration of 'struct drm_device *dev' is redundant, as
'connector->dev' & 'dev_get_drvdata(kdev)' can be directly passed to
'drm_to_adev', without intermediate DRM device 'dev' variable
