From: Imre Deak Date: Thu, 8 Jan 2015 15:54:13 +0000 (+0200) Subject: drm/i915: add dev_to_i915 helper X-Git-Tag: v3.19.3~42 X-Git-Url: http://git.hungrycats.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=61e975e46864cbcf7707c980173bc7efe781edb5;p=linux drm/i915: add dev_to_i915 helper commit 888d0d421663313739a8bf93459c6ba61fd4b121 upstream. This will be needed by later patches, so factor it out. No functional change. v2: - s/dev_to_i915_priv/dev_to_i915/ (Jani) - don't use the helper in i915_pm_suspend (Chris) - simplify the helper (Chris) v3: - remove redundant upcasting in the helper (Daniel) Signed-off-by: Imre Deak Reviewed-by: Takashi Iwai Signed-off-by: Daniel Vetter Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c index 7643300828c3..489b220af02b 100644 --- a/drivers/gpu/drm/i915/i915_drv.c +++ b/drivers/gpu/drm/i915/i915_drv.c @@ -934,8 +934,7 @@ static int i915_pm_suspend(struct device *dev) static int i915_pm_suspend_late(struct device *dev) { - struct pci_dev *pdev = to_pci_dev(dev); - struct drm_device *drm_dev = pci_get_drvdata(pdev); + struct drm_device *drm_dev = dev_to_i915(dev)->dev; /* * We have a suspedn ordering issue with the snd-hda driver also @@ -954,8 +953,7 @@ static int i915_pm_suspend_late(struct device *dev) static int i915_pm_resume_early(struct device *dev) { - struct pci_dev *pdev = to_pci_dev(dev); - struct drm_device *drm_dev = pci_get_drvdata(pdev); + struct drm_device *drm_dev = dev_to_i915(dev)->dev; if (drm_dev->switch_power_state == DRM_SWITCH_POWER_OFF) return 0; @@ -965,8 +963,7 @@ static int i915_pm_resume_early(struct device *dev) static int i915_pm_resume(struct device *dev) { - struct pci_dev *pdev = to_pci_dev(dev); - struct drm_device *drm_dev = pci_get_drvdata(pdev); + struct drm_device *drm_dev = dev_to_i915(dev)->dev; if (drm_dev->switch_power_state == DRM_SWITCH_POWER_OFF) return 0; diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 0936b0f94826..ddd005ce3a94 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -1781,6 +1781,11 @@ static inline struct drm_i915_private *to_i915(const struct drm_device *dev) return dev->dev_private; } +static inline struct drm_i915_private *dev_to_i915(struct device *dev) +{ + return to_i915(dev_get_drvdata(dev)); +} + /* Iterate over initialised rings */ #define for_each_ring(ring__, dev_priv__, i__) \ for ((i__) = 0; (i__) < I915_NUM_RINGS; (i__)++) \
