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

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