drivers/rtc/rtc-tegra.c: protect suspend/resume callbacks with CONFIG_PM_SLEEP
CONFIG_PM doesn't actually enable any of the PM callbacks, it only allows
to enable CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME. This means if CONFIG_PM
is used to protect system sleep callbacks then it may end up unreferenced
if only runtime PM is enabled. Hence protecting sleep callbacks with
CONFIG_PM_SLEEP.

init: scream bloody murder if interrupts are enabled too early
As I was testing a lot of my code recently, and having several
"successes", I accidentally noticed in the dmesg this little line:
start_kernel(): bug: interrupts were enabled *very* early, fixing it
Sure enough, one of my patches two commits ago enabled interrupts early.
The sad part here is that I never noticed it, and I ran several tests with
ktest too, and ktest did not notice this line.
What ktest looks for (and so does many other automated testing scripts) is
a back trace produced by a WARN_ON() or BUG(). As a back trace was never
produced, my buggy patch could have slipped into linux-next, or even
worse, mainline.
Adding a WARN(!irqs_disabled()) makes this bug a little more obvious:

argv_split(): teach it to handle mutable strings
argv_split() allocates argv[count_argc(str)] array and assumes that it
will find the same number of arguments later. This is obviously wrong if
this string can be changed, say, by sysctl.
With this patch argv_split() kstrndup's the whole string and does not
split it, we simply replace the spaces with zeroes and keep the allocated
memory in argv[-1] for argv_free(arg).
We do not use argv[0] because:
- str can be all-spaces or empty. In fact this case is fine,
we could kfree() it before return, but:
- str can have a space at the start, and we can not rely on
kstrndup(skip_spaces(str)) because it can equally race if
this string is mutable.
Also, simplify count_argc() and kill the no longer used skip_arg().

Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management. Also, use of
pm_message_t is deprecated. Thus, it is removed.

drivers/video/backlight/platform_lcd.c: introduce probe callback
Platform LCD devices may need to do some device-specific initialization
before they can be used (regulator or GPIO setup, for example), but
currently the driver does not support any way of doing this. This patch
adds a probe() callback to plat_lcd_data which platform LCD devices can
set to indicate that device-specific initialization is needed.
