Emitting an OOM message isn't necessary after input_allocate_device
as there's a generic OOM and a dump_stack already done.

Pull ARM SoC multiplatform updates from Olof Johansson:
"More multiplatform enablement for ARM platforms. The ones converted
in this branch are:
- bcm2835
- cns3xxx
- sirf
- nomadik
- msx
- spear
- tegra
- ux500
We're getting close to having most of them converted!
One of the larger platforms remaining is Samsung Exynos, and there are
a bunch of supporting patches in this merge window for it. There was
a patch in this branch to a early version of multiplatform conversion,
but it ended up being reverted due to need of more bake time. The
revert commit is part of the branch since it would have required
rebasing multiple dependent branches and they were stable by then"

There is only one instance of the platform data for synaptics_i2c_rmi4
in the mainline kernel, so there is no point of pretending its
variable here. The only member that has a dependency on the platform
is actually the interrupt number, and there is a field in the
i2c_client structure that gets initialized from the board info,
so we can trivially move the board_into into the platform without
knowledge of the platform_data structure.

alloc failures already get standardized OOM
messages and a dump_stack.
For the affected mallocs around these OOM messages:
Converted kzallocs with multiplies to kcalloc.
Converted kmallocs with multiplies to kmalloc_array.
Converted a kmalloc/strlen/strncpy to kstrdup.
Moved a spin_lock below a removed OOM message and
removed a now unnecessary spin_unlock.
Neatened alignment and whitespace.

Pull "ARM: More device tree support updates" from Olof Johansson:
"This branch contains a number of updates for device tree support on
several ARM platforms, in particular:
* AT91 continues the device tree conversion adding support for a
number of on-chip drivers and other functionality
* ux500 adds probing of some of the core SoC blocks through device
tree
* Initial device tree support for ST SPEAr600 platforms
* kirkwood continues the conversion to device-tree probing"
Manually merge arch/arm/mach-ux500/Kconfig due to MACH_U8500 rename, and
drivers/usb/gadget/at91_udc.c due to header file include cleanups.
Also do an "evil merge" for the MACH_U8500 config option rename that the
affected RMI4 touchscreen driver in staging. It's called MACH_MOP500
now, and it was missed during previous merges.

Lots of people expect module.h to just "be there" without
any #include effort. But we are crushing that. So fix those
files in staging relying on implicit module.h presence.

The ux500 machine was actually defining platform data for the
staging driver ste_rmi4, which is not OK. Let us instead define
some __weak platform data in the machine so that the staging
driver can override it at compile-time and we can thus have the
driver self-contained in staging.

The original code called input_free_device(rmi4_data->input_dev) after
input_unregister_device(rmi4_data->input_dev) and that's a double free.
This is described in the comments to input_unregister_device().
The normal way to handle this is to make input_register_device() the
last function in the probe which can fail. That way you can avoid the
call to input_unregister_device() entirely.
