of_node_put is needed before discarding a value received from
of_find_node_by_name, eg in error handling code or when the device node is
no longer used.
The semantic match that catches the bug is as follows:

It is always "an" if there is a vowel _spoken_ (not written).
So it is:
"an hour" (spoken vowel)
but
"a uniform" (spoken 'j')

This splits the mmu_context handling between 32-bit hash based
processors, 64-bit hash based processors and everybody else. This is
preliminary work for adding SMP support for BookE processors.

device_create() is race-prone, so use the race-free
device_create_drvdata() instead as device_create() is going away.

This makes two changes:
* As noted by Akinobu Mita in patch
b1fceac2b9, alloc_bootmem never returns NULL
and always returns a zeroed region of memory. Thus the error checking code
and memset after the call to alloc_bootmem are not necessary.
* The old error handling code consisted of setting a global variable to
NULL and returning an error code, which could cause previously allocated
resources never to be freed. The patch adds calls to appropriate resource
deallocation functions.

This contains the following cleanups:
- make the following needlessly global code static:
- adb.c: adb_controller
- adb.c: adb_init()
- adbhid.c: adb_to_linux_keycodes[] (also make it const)
- via-pmu68k.c: backlight_level
- via-pmu68k.c: backlight_enabled
- remove the following unused code:
- via-pmu68k.c: sleep_notifier_list
