X-Git-Tag: for-4.21~67^2~15^2~220
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7b5543015bbd31104be63dd9cf5cb6ad8e61fe17;p=uclinux-h8%2Flinux.git

drm/i915/sdvo: Utilize intel_panel for fixed_mode

Remove the local lvds fixed mode pointer from the sdvo encoder
structure and instead utilize intel_panel like everyone else.

v2: intel_sdvo_destroy() is gone
