From f4448375467d9443a1e74e0552212121b6394332 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 28 Oct 2015 23:59:02 +0200 Subject: drm/i915/gen9: Use dev_priv in csr functions As all csr firmware related opertion are not using any any data structures of drm framework level, so better to use dev_priv instead of dev. it's a new style! :) Cc: Damien Lespiau Cc: Imre Deak Cc: Sunil Kamath Signed-off-by: Daniel Vetter Signed-off-by: Animesh Manna Signed-off-by: Imre Deak Tested-by: Daniel Stone # SKL Signed-off-by: Jani Nikula Link: http://patchwork.freedesktop.org/patch/msgid/1446069547-24760-9-git-send-email-imre.deak@intel.com diff --git a/drivers/gpu/drm/i915/i915_dma.c b/drivers/gpu/drm/i915/i915_dma.c index 76a53e8..66e6a1f 100644 --- a/drivers/gpu/drm/i915/i915_dma.c +++ b/drivers/gpu/drm/i915/i915_dma.c @@ -426,7 +426,7 @@ static int i915_load_modeset_init(struct drm_device *dev) intel_power_domains_init_hw(dev_priv);
