This patch set replaces the occurrences of drm_*_reference() and
drm_*_unreference() with the new drm_*_get() and drm_*_put() functions.
All patches in the series do the same thing, converting to the new APIs.
I created patches per DRM driver as suggested by Daniel Vetter.
Background:
In the kernel, reference counting APIs use *_get(), *_put() style naming
to reference-count the objects. But DRM subsystem uses a different
naming for them such as *_reference(), *_unreference() which is
inconsistent with the other reference counting APIs in the kernel. To
solve this consistency issue, Thierry Reding introduced a couple of
functions and compatibility aliases in the following commits for them.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() adn should not be
used by new code. So convert all users of compatibility functions to use
the new APIs.

Please include the cocci script in the commit message. If you didn't use
cocci, you should check it out! :)

Yeah I assume you've created these with spatch/cocci, not with your own
script. I trust cocci a lot more than any kind of scripting, and the
coccie patch is already in there kernel (the commits you've cited in the
cover letter contain it iirc).

Indeed I used a simple shell script, which I included in the cover
letter. But the cover letter doesn't seem to show up in the mailing
list archives for some reason. I think I have done something wrong.
The script I use is like:
path=$1
do_replace() {
local pattern=$1
local replacement=$2
git grep -lw "${pattern}" -- "${path}/*.[hc]" |\
xargs -r sed -i "s/\b$pattern\b/$replacement/g"
}
do_replace drm_mode_object_reference drm_mode_object_get
do_replace drm_mode_object_unreference drm_mode_object_put
do_replace drm_connector_reference drm_connector_get
do_replace drm_connector_unreference drm_connector_put
do_replace drm_framebuffer_reference drm_framebuffer_get
do_replace drm_framebuffer_unreference drm_framebuffer_put
do_replace drm_gem_object_reference drm_gem_object_get
do_replace drm_gem_object_unreference drm_gem_object_put
do_replace __drm_gem_object_unreference __drm_gem_object_put
do_replace drm_gem_object_unreference_unlocked drm_gem_object_put_unlocked
do_replace drm_property_reference_blob drm_property_blob_get
do_replace drm_property_unreference_blob drm_property_blob_put
I had used the coccinelle in report mode for staging tree. It reported
about staging: vboxvideo driver. In this way I saw there is a need to
change to the new APIs.
I used my own script because I haven't used coccinelle in patch mode
before.

I wrote a simple shell script, which you can see in the cover letter.
But you are right I take function list from scripts/coccinelle/api/drm-get-put.cocci
file.
Daniel Should I use coccinelle to generate patches and resend a v2?
If so, do i need to include reviewed-by and acked-by tags to patches myself?
Thanks.

For intel-gfx it was in moderation, I let it through now.

I think regenerating the patches using cocci would be great, I trust
cocci a lot more than random scripts. And cocci is a great tool to
learn anyway (if you don't know it yet). If the resulting patches
match, you can keep the r-b/a-b tags for v2.
Thanks, Daniel
