+Subject: drm: remove FASYNC support
+
+So I've stumbled over drm_fasync and wondered what it does. Digging
+that up is quite a story.
+
+First I've had to read up on what this does and ended up being rather
+bewildered why peopled loved signals so much back in the days that
+they've created SIGIO just for that ...
+
+Then I wondered how this ever works, and what that strange "No-op."
+comment right above it should mean. After all calling the core fasync
+helper is pretty obviously not a noop. After reading through the
+kernels FASYNC implementation I've noticed that signals are only sent
+out to the processes attached with FASYNC by calling kill_fasync.
+
+No merged drm driver has ever done that.
+
+After more digging I've found out that the only driver that ever used
+this is the so called GAMMA driver. I've frankly never heard of such a
+gpu brand ever before. Now FASYNC seems to not have been the only bad
+thing with that driver, since Dave Airlie removed it from the drm
+driver with prejudice:
+
+commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed
+Author: Dave Airlie <airlied@linux.ie>
+Date: Sun Aug 29 12:04:35 2004 +0000
+
+ Drop GAMMA DRM from a great height ...
+
+Long story short, the drm fasync support seems to be doing absolutely
+nothing. And the only user of it was never merged into the upstream
+kernel. And we don't need any fops->fasync callback since the fcntl
+implementation in the kernel already implements the noop case
+correctly.
+
+So stop this particular cargo-cult and rip it all out.
+
+v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers
+(somehow I've missed that one in staging). Also drop the reference in
+the drm DocBook. ARM compile-fail reported by Rob Clark.
+
+v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this
+patch here.
+
+v4: Actually git add ... tsk.

+Subject: drm/gem: create drm_gem_dumb_destroy
+
+All the gem based kms drivers really want the same function to
+destroy a dumb framebuffer backing storage object.
+
+So give it to them and roll it out in all drivers.
+
+This still leaves the option open for kms drivers which don't use GEM
+for backing storage, but it does decently simplify matters for gem
+drivers.

+Subject: fb: make fp_get_options name argument const
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+drm_get_connector_name now returns a const value, which causes the following
+compilation warning:
+
+ drivers/gpu/drm/drm_fb_helper.c: In function ‘drm_fb_helper_parse_command_line’:
+ drivers/gpu/drm/drm_fb_helper.c:127:3: warning: passing argument 1 of ‘fb_get_options’ discards ‘const’ qualifier from pointer target type [enabled by default]
+ In file included from drivers/gpu/drm/drm_fb_helper.c:35:0:
+ include/linux/fb.h:627:12: note: expected ‘char *’ but argument is of type ‘const char *’
+
+As fb_get_options uses its name argument as read only, make it const. This
+fixes the aforementioned compilation warning.

+Subject: i2c: mv64xxx: Do not use writel_relaxed()
+
+The driver is used on PowerPC which don't provide writel_relaxed(). This
+breaks the c2k and prpmc2800 default configurations. To fix the build,
+turn the calls to writel_relaxed() into writel(). The impacts for ARM
+should be minimal.
