sh: Fix up more fallout from pointless ARM __iomem churn.

It was already pointed out how to fix these cases before the offending
patches were merged, but unsurprisingly, that didn't happen. As this
change is entirely superfluous to begin with, simply shut things up by
casting everything away.

pinctrl: samsung: use __devinit section for init code

The samsung pinctrl driver has a probe function that is
__devinit and that calls a lot of other functions that are
marked __init, which kbuild complains about.

Marking everything __devinit means that the code does not
discarded when CONFIG_HOTPLUG is set, which is a little
more wasteful, but also more consistent

Without this patch, building exynos_defconfig results in:

WARNING: drivers/pinctrl/built-in.o(.devinit.text+0x124): Section mismatch in reference from the function samsung_pinctrl_probe() to the function .init.text:samsung_gpiolib_register()
The function __devinit samsung_pinctrl_probe() references
a function __init samsung_gpiolib_register().
If samsung_gpiolib_register is only used by samsung_pinctrl_probe then
annotate samsung_gpiolib_register with a matching annotation.

pinctrl: sirf: remove sirfsoc_gpio_set_pull function

The prima2 platform advertises needing no mach/gpio.h header file,
but its pinctrl driver now has a sirfsoc_gpio_set_pull function
that uses constants defined in arch/arm/mach-prima2/include/mach/gpio.h,
which fails to build.

Fortunately, the sirfsoc_gpio_set_pull is not used anywhere in the
kernel, so we can safely remove it. Any out of tree drivers using
it will have to be converted to use proper pinctrl functions to
do the same.

Without this patch, building prima2_defconfig results in:

drivers/pinctrl/pinctrl-sirf.c: In function 'sirfsoc_gpio_set_pull':
drivers/pinctrl/pinctrl-sirf.c:1331:7: error: 'SIRFSOC_GPIO_PULL_NONE' undeclared (first use in this function)

pinctrl/nomadik: provide stubs for legacy Nomadik

The compilation of the pinctrl driver failed on the legacy
Nomadik NHK8815 platform because it was not providing the PRCMU
interfaces needed to support the extended alternate functions
used by the ux500 series.

Solve this by providing some stubs for the legacy platform, to
avoid too much #ifdefs in the code per se. Theoretically this
actually allows the Nomadik and Ux500 to have a single kernel
image with support for the PRCM registers on the Ux500 (though
they have incompatible archs, but the spirit is there).

usb: dwc3: gadget: fix 'endpoint always busy' bug

If a USB transfer has already been started, meaning
we have already issued StartTransfer command to that
particular endpoint, DWC3_EP_BUSY flag has also
already been set.

When we try to cancel this transfer which is already
in controller's cache, we will not receive XferComplete
event and we must clear DWC3_EP_BUSY in order to allow
subsequent requests to be properly started.

The best place to clear that flag is right after issuing
DWC3_DEPCMD_ENDTRANSFER.

usb: musb: am35xx: drop spurious unplugging a device

On AM3517, tx and rx interrupt are detected together with
the disconnect event. This generates a kernel panic in musb_interrupt,
because rx / tx are handled after disconnect.
This issue was seen on a Technexion's TAM3517 SOM. Unplugging a device,
tx / rx interrupts together with disconnect are detected. This brings
to kernel panic like this:

the board.

Drop tx / rx interrupts if disconnect is detected.
