Some of them are pretty good catches, such as gpio.c:56 and
usb-tusb6010.c:129.
Thanks to Jarkko Nikula for some comments on the sscanf() warnings.
It seems that the kernel sscanf() ignores the field width anyway for the
%d format, so those changes have been dropped from this second version.
Thanks to Daniel Marjamäki <daniel.marjamaki@gmail.com> for pointing
out that a variable was unnecessarily marked static in the
board-omap3evm.c change.

gcc can apparently handle stack-allocated arrays that use a dynamic
variable as the array maximum. Rather than using a mutable quantity,
simply use a constant maximum possible size. To me, code clarity is
improved; and it also avoids the following sparse warnings:
arch/arm/plat-omap/dma.c:886:40: error: bad constant expression
arch/arm/plat-omap/dma.c:892:17: error: cannot size expression
arch/arm/plat-omap/dma.c:970:40: error: bad constant expression
arch/arm/plat-omap/dma.c:972:17: error: cannot size expression
Also drop some dead code from the OMAP1 LCD DMA code:
arch/arm/mach-omap1/lcd_dma.c:80:6: warning: symbol 'omap_set_lcd_dma_src_port' was not declared. Should it be static?

Pull "ARM: global cleanups" from Arnd Bergmann:
"Quite a bit of code gets removed, and some stuff moved around, mostly
the old samsung s3c24xx stuff. There should be no functional changes
in this series otherwise. Some cleanups have dependencies on other
arm-soc branches and will be sent in the second round.

Fixed up trivial conflicts mainly due to #include's being changes on
both sides.

There's no need to have these in plat/io.h.
While at it, clean up the includes to group them
like they typically are grouped.

This patch fixes bug introduced in revision:
f8e9e98454606e43b728269de21db349f57861c7
omap1: DMA: move LCD related code from plat-omap to mach-omap1
The code introduced by this patch didn't consider any other CPUs but OMAP1510,
which rendered OMAP310 -- which has the same LCD controller -- non-working. Use
cpu_is_omap15xx() instead of cpu_is_omap1510() to squash this issue.
Bug found on Palm Zire 71 hardware.

The patch corrects the issue introduced with one of my earlier patches:
OMAP: DMA: Fix omapfb/lcdc on OMAP1510 broken when PM set[1]
as pointed out by OMAP subsystem maintainer.
Applies on top of my prevoius patch:
OMAP: DMA: move LCD DMA related code from plat-omap to mach-omap1[2]
Tested on Amstrad Delta
Compile tested with omap_generic_2420_defconfig

All of the LCD DMA code in plat-omap/dma.c appears to be OMAP1-only (and
apparently only is available on a subset of OMAP1 chips).
Move this code to mach-omap1/lcd_dma.c.
Tested on OMAP1510 Amstrad Delta.
Compile-tested with omap_generic_2420_defconfig.
