sysdev_class_register should check the kobject_set_name return value.

Add the return value checking code.

Sysdevs have to be suspended and resumed with interrupts disabled and
things usually break in a way that's difficult to debug if one of
sysdev drivers enables interrupts by mistake during suspend or
resume.  Add extra checks that will generate warnings in such cases.

Use the functions introduced in by the previous patch,
suspend_device_irqs(), resume_device_irqs() and check_wakeup_irqs(),
to rework the handling of interrupts during suspend (hibernation) and
resume.  Namely, interrupts will only be disabled on the CPU right
before suspending sysdevs, while device drivers will be prevented
from receiving interrupts, with the help of the new helper function,
before their "late" suspend callbacks run (and analogously during
resume).

In addition, since the device interrups are now disabled before the
CPU has turned all interrupts off and the CPU will ACK the interrupts
setting the IRQ_PENDING bit for them, check in sysdev_suspend() if
any wake-up interrupts are pending and abort suspend if that's the
case.

Impact: module build fix

Fix:

 ERROR: "sysdev_resume" [arch/x86/kernel/apm.ko] undefined!
 ERROR: "sysdev_suspend" [arch/x86/kernel/apm.ko] undefined!

As these APIs are now used by the APM driver, which can be built
as a module.

Also fix a few extra (and inconsistent) newlines in comment blocks
preceding these functions.

SYSFS: Fix return values for sysdev_store_{ulong,int}

Always return the full size instead of the consumed
length of the string in sysdev_store_{ulong,int}

This avoids EINVAL errors in some echo versions.
