From: Chris Wilson Date: Wed, 20 Jul 2016 12:31:50 +0000 (+0100) Subject: drm/i915: Rename i915_gem_context_reference/unreference() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9a6feaf0d74f91eeef23d0ee72c5ce69a559b31b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Rename i915_gem_context_reference/unreference() As these are wrappers around kref_get/kref_put() it is preferable to follow the naming convention and use the same verb get/put in our wrapper names for manipulating a reference to the context. s/i915_gem_context_reference/i915_gem_context_get/ s/i915_gem_context_unreference/i915_gem_context_put/ Signed-off-by: Chris Wilson Cc: Tvrtko Ursulin Cc: Joonas Lahtinen Reviewed-by: Joonas Lahtinen Link: http://patchwork.freedesktop.org/patch/msgid/1469005202-9659-3-git-send-email-chris@chris-wilson.co.uk Link: http://patchwork.freedesktop.org/patch/msgid/1469017917-15134-2-git-send-email-chris@chris-wilson.co.uk --- diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index e163a9487750..2131e7f1e57a 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -3338,12 +3338,14 @@ i915_gem_context_lookup(struct drm_i915_file_private *file_priv, u32 id) return ctx;
