[PATCH v3 0/3] drm/msm: Replace {un/reference} with {put, get} functions

[PATCH v3 0/3] drm/msm: Replace {un/reference} with {put, get} functions

[Thomas Zimmermann]

This patch set replaces functions named {un,reference} by their
{put,get} counterparts. Affected data types are struct struct drm_framebuffer,
struct drm_gem_object, and struct drm_device.

With the reference-counting functions being named {put,get}, the DRM
interface is more aligned to Linux kernel nameing standard. The patch
set does not change driver-internal interfaces.

Changes since v2:
	* fixed an instance in a6xx_destroy()

Changes since v1:
	* rebased on 4.18
	* adapted to changes in msm_drv.c and adreno/a5xx_gpu.c

Thomas Zimmermann (3):
  drm/msm: Replace drm_framebuffer_{un/reference} with put,get functions
  drm/msm: Replace drm_gem_object_{un/reference} with put,get functions
  drm/msm: Replace drm_dev_unref with drm_dev_put

[PATCH v3 1/3] drm/msm: Replace drm_framebuffer_{un/reference} with put, get functions

[Thomas Zimmermann]

This patch unifies the naming of DRM functions for reference counting
of struct drm_framebuffer. The resulting code is more aligned with the
rest of the Linux kernel interfaces.

Care to review all 3 and then push them? Or is msm still not yet group
maintained :-)

[PATCH v3 3/3] drm/msm: Replace drm_dev_unref with drm_dev_put

[Thomas Zimmermann]

This patch unifies the naming of DRM functions for reference counting
of struct drm_device. The resulting code is more aligned with the rest
of the Linux kernel interfaces.
