[PATCH v2 0/8] ARM: mostly harmless gcc warnings

[PATCH v2 0/8] ARM: mostly harmless gcc warnings

[Arnd Bergmann]

Most patches from the first time this was posted have been
adopted by a subsystem maintainer or were show to be obsolete.
Here are the remaining ones again.

I'm planning to submit those patches that are still necessary
by the time we have an -rc1 through the arm-soc tree, but
my preference is still to have them go through the subsystem
maintainers.

Olof: should we add it to for-next?

[PATCH v2 7/8] video: mark nuc900fb_map_video_memory as __devinit

[Arnd Bergmann]

nuc900fb_map_video_memory is called by an devinit function
that may be called at run-time, but the function itself is
marked __init and will be discarded after boot.

To avoid calling into a function that may have been overwritten,
mark nuc900fb_map_video_memory itself as __devinit.

Without this patch, building nuc950_defconfig results in:

WARNING: drivers/video/built-in.o(.devinit.text+0x26c): Section mismatch in reference from the function nuc900fb_probe() to the function .init.text:nuc900fb_map_video_memory()
The function __devinit nuc900fb_probe() references
a function __init nuc900fb_map_video_memory().
If nuc900fb_map_video_memory is only used by nuc900fb_probe then
annotate nuc900fb_map_video_memory with a matching annotation.
