Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit. Fix it by replacing with scnprintf().

It seems that the default case should return AE_CTRL_TERMINATE, instead
of falling through to case ACPI_RESOURCE_TYPE_END_TAG and returning AE_OK;
otherwise the line of code at the end of the function is unreachable and
makes no sense:
return AE_CTRL_TERMINATE;
This fix is based on the following thread of discussion:

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.
Casting from unsigned long:
void my_callback(unsigned long data)
{
struct something *ptr = (struct something *)data;
...
}
...
setup_timer(&ptr->my_timer, my_callback, ptr);
and forced object casts:
void my_callback(struct something *ptr)
{
...
}
...
setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);
become:
void my_callback(struct timer_list *t)
{
struct something *ptr = from_timer(ptr, t, my_timer);
...
}
...
timer_setup(&ptr->my_timer, my_callback, 0);
Direct function assignments:
void my_callback(unsigned long data)
{
struct something *ptr = (struct something *)data;
...
}
...
ptr->my_timer.function = my_callback;
have a temporary cast added, along with converting the args:
void my_callback(struct timer_list *t)
{
struct something *ptr = from_timer(ptr, t, my_timer);
...
}
...
ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;
And finally, callbacks without a data assignment:
void my_callback(unsigned long data)
{
...
}
...
setup_timer(&ptr->my_timer, my_callback, 0);
have their argument renamed to verify they're unused during conversion:
void my_callback(struct timer_list *unused)
{
...
}
...
timer_setup(&ptr->my_timer, my_callback, 0);
The conversion is done with the following Coccinelle script:

Source code review for a specific software refactoring showed the need
for another correction because the error code "-1" was returned so far
if a call of the function "sony_call_snc_handle" failed here.
Thus assign the return value from these two function calls also to
the variable "err" and provide it in case of a failure.

current_fs_time() uses struct super_block* as an argument.
As per Linus's suggestion, this is changed to take struct
inode* as a parameter instead. This is because the function
is primarily meant for vfs inode timestamps.
Also the function was renamed as per Arnd's suggestion.
Change all calls to current_fs_time() to use the new
current_time() function instead. current_fs_time() will be
deleted.

Port the backlight selection logic to the new backlight interface
selection API.
This commit also removes various obsolete pr_xxx messages related to
backlight interface selection. These are obsolete because they assume
there is only a vendor or acpi backlight driver and no other choice.
Also they are not necessary, if the user wants to know which backlight
interfaces are registered a simple "ls /sys/class/backlight" suffices.

Keyboard backlight can be always off, use some automatic trigger
(activity and light sensor), always on.
The behaviour of the driver changes whereby previously when passed 1 it
tried to turn on backlight immediately now it does nothing. This is
however a bug fix since (a) it makes little sense to turn on the
backlight when control is automatic and (b) this behaviour is
consistent with what the windows driver does.

Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.
First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.
Second, there are ordering dependencies between those files that always
have to be met. Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there. And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds. That also is taken care of including
<linux/acpi.h> as appropriate.

Follow-up to commit 294d31e8227c ("sony-laptop: don't change keyboard
backlight settings"): avoid messing up the state on resume. Leave it to
what was before suspending as it's anyway likely that we still don't
know what value we should write to the EC registers. This fix is also
required in 3.12

Some BIOS versions/Vaio models apparently ship with two nearly identical
functions to handle backlight related controls.
The only difference seems to be:
If (LEqual (BUF1, 0x40))
{
Store (0x40, P80H)
Store (BUF2, Local0)
- And (Local0, One, Local0)
+ And (Local0, 0x03, Local0)
Store (Local0, ^^H_EC.KLPC)
}
Avoid erroring out on initialization and messing things up on cleanup
for now since we never call into these methods with anything different
than 1 or 0.
This issue was found on a Sony VPCSE1V9E/BIOS R2087H4.

Do not touch keyboard backlight unless explicitly passed a module
parameter. In this way we won't make wrong assumptions about what are
good default values since they actually are different from model to
model.
The only side effect is that we won't know what is the current value
until set via the sysfs attributes.

acpi_has_method() is a new ACPI API introduced to check
the existence of an ACPI control method.
It can be used to replace acpi_get_handle() in the case that
1. the calling function doesn't need the ACPI handle of the control method.
and
2. the calling function doesn't care the reason why the method is unavailable.
Convert acpi_get_handle() to acpi_has_method()
in drivers/platform/x86/sony-laptop.c in this patch.
