Ville Syrjälä b00cb5a350 drm/i915: Fix init_clock_gating for resume ... commit 3572f04c69 upstream. Moving the init_clock_gating() call from intel_modeset_init_hw() to intel_modeset_gem_init() had an unintended effect of not applying some workarounds on resume. This, for example, cause some kind of corruption to appear at the top of my IVB Thinkpad X1 Carbon LVDS screen after hibernation. Fix the problem by explicitly calling init_clock_gating() from the resume path. I really hope this doesn't break something else again. At least the problems reported at https://bugs.freedesktop.org/show_bug.cgi?id=103549 didn't make a comeback, even after a hibernate cycle. v2: Reorder the init_clock_gating vs. modeset_init_hw to match the display reset path (Rodrigo) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Fixes: 6ac4327276 ("drm/i915: Move init_clock_gating() back to where it was") Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20171116160215.25715-1-ville.syrjala@linux.intel.com Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> (cherry picked from commit 675f7ff35b) Signed-off-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2018-01-17 09:45:25 +01:00
