[PATCH 0/8] sa1100fb updates

From: linux@armlinux.org.uk (Russell King - ARM Linux)
Date: 2017-09-29 10:50:04 

Hi Bart,

This series updates the sa1100fb fbdev driver's initialisation paths
to be more robust.  In doing these updates, I realised that we omitted
to free some memory which was allocated for the framebuffer if
initialisation fails - something that was hidden due to the complex
cleanup that the driver performs.  Switching to managed resources made
this more obvious.

Tested on H3600 iPAQ and Assabet.

[PATCH 1/8] video: sa1100fb: use devm_kzalloc()

From: Russell King <hidden>
Date: 2017-09-29 10:50:56 

Use devm_kzalloc() when allocating the private data for the framebuffer
device.

[PATCH 3/8] video: sa1100fb: use devm_ioremap_resource()

From: Russell King <hidden>

Use devm_ioremap_resource() to map the LCD controller memory region,
and remove the unnecessary cleanup for this.

so we can avoid having to manually clean this up.

[PATCH 5/8] video: sa1100fb: use devm_gpio_request_one()

From: Russell King <hidden>
Date: 2017-09-29 10:51:17 

Switch to using devm_gpio_request_one() to request the shannon gpio
and move the request before the video memory allocation, so we request
all device managed resources before this large allocation attempt.

We merely return from the failed path, so remove all the gotos and use
return statements instead.

cleanup that the driver performs.  Switching to managed resources made
this more obvious.

Tested on H3600 iPAQ and Assabet.

I queued all patches for 4.15, thanks!
Now that 4.15-rc1 is out, something tells me that was not actually
the case.  Any ideas what happened?
Could you please explain the issue that you are seeing a bit more?

For me it looks all fine:

$ git log --oneline v4.15-rc1 drivers/video/fbdev/sa1100fb.c
cb6bc3f video: sa1100fb: move pseudo palette into sa1100fb_info structure
0ab7658 video: sa1100fb: fix video memory allocation leak
c244f8e video: sa1100fb: clean up failure path

f6fc8c9 video: sa1100fb: use devm_request_irq()
df6b228 video: sa1100fb: use devm_ioremap_resource()
e43064c video: sa1100fb: use devm_clk_get()
ba1d36b video: sa1100fb: use devm_kzalloc()
...
Looks like I hadn't rebased that particular branch, so they were still
showing up in my origin.. git log.  Sorry about the false warning.

This is the problem of carrying close to 400 patches in separate
branches, and git log origin.. not able to show the commits that the
selection are based upon.
