Two additional savage4 variants were added, but the S3_SAVAGE4_SERIES
macro was incompletely modified, resulting in a false positive detection
of a savage4 card regardless of which savage card is actually present.
For non-savage4 series cards, such as a Savage/IX-MV card, this results
in garbled video and/or a hard-hang at boot time. Fix this by changing
an '||' to an '&&' in the S3_SAVAGE4_SERIES macro.

Currently the use of pm_runtime_put_sync() is not safe from
interrupts-disabled context because rpm_idle() will release the
spinlock and enable interrupts for the idle callbacks. This enables
interrupts during a time where interrupts were expected to be
disabled, and can have strange side effects on drivers that expected
interrupts to be disabled.
This is not a bug since the documentation clearly states that only
_put_sync_suspend() is safe in IRQ-safe mode.
However, pm_runtime_put_sync() could be made safe when in IRQ-safe
mode by releasing the spinlock but not re-enabling interrupts, which
is what this patch aims to do.
Problem was found when using some buggy drivers that set
pm_runtime_irq_safe() and used _put_sync() in interrupts-disabled
context.

The local variable ret is defined twice in pm_genpd_poweron(), which
causes this function to always return 0, even if the PM domain's
.power_on() callback fails, in which case an error code should be
returned.
Remove the wrong second definition of ret and additionally remove an
unnecessary definition of wait from pm_genpd_poweron().

The AMW0 function in acer-wmi works on Lenovo ideapad S205 for control

exposes the state of wifi hardware switch on the machine.
So, add this patch to support Lenovo ideapad S205 wifi hardware switch
in acer-wmi driver.

This key is different than other hotkeys, having seperate scan
codes for press, release, and hold, so it requires some special
filtering. Press and release events are passed on, and hold events
are ignored since sparse-keymap does not support hardware
autorepeat.
Note that "Home" in the context of this button doesn't mean the
same thing as the usual Home key, and it really isn't clear at
all what is meant by "Home". The manufacurer's description of the
button indicates that it should launch some sort of touch screen
settings interface on short press and apply a desktop rotation on
long press.

we can now autodetect internal 3G device and already have the threeg

longer necessary.
We also plan to remove interface sysfs file that exposed which ACPI-WMI
interface that was used by acer-wmi driver. It will replaced by information
log when acer-wmi initial.
We keep it around for userspace compatibility reasons, schedule removal
in 2012.
