This works around what I think is actually a bug in rt2860sta which is
triggered when the hardware "disappears" from beneath the driver, i.e. when
wireless is toggled off via ACPI. It does so by ensuring that the rfkill
soft-block flag is set before the hardware is disabled.
I do not know whether this patch is required if rt2800pci is in use instead
of rt2860sta; at the time of submission of this patch, I've not been able to
test this.

Currently the annotation for function eeepc_enable_camera() is
__init, and refers to a
function eeepc_hotk_add() which is non-init. Use __devinit for both
functions which is
more appropriate and fixes a section mismatch warning.
We were warned by the following warning:
LD drivers/platform/x86/built-in.o
WARNING: drivers/platform/x86/built-in.o(.text+0x12e1): Section
mismatch in reference from the function eeepc_hotk_add() to the
function .init.text:eeepc_enable_camera()
The function eeepc_hotk_add() references
the function __init eeepc_enable_camera().
This is often because eeepc_hotk_add lacks a __init
annotation or the annotation of eeepc_enable_camera is wrong.

"I recently (on a flight) I found out that when I boot with the hard-switch
activated, so turning off all wireless activity on my laptop, the state
is not correctly announced in /dev/rfkill (reading it with rfkill command,
or my own gnome applet)...
After turning off and on again the hard-switch the events were right."
We can fix this by querying the firmware at load time and calling
rfkill_set_hw_state().

The SPIC irq is not really shareable, the IO port cannot be cleared and
always returns some data so there is no real way to understand if the irq
is for us or not. Moreover the _PRS acpi method says the irq is not
shareable.
In addition to this, in some cases, an additional write to the IO port has
to be performed in order to properly decode the event received from the
device. This generates another interrupt which may overlap with the
previous one. In the future this is going to be important for properly
decoding events.

Update the HKEY event driver to:
1. Handle better the second-gen firmware, which has no HKEY mask
support but does report FN+F3, FN+F4 and FN+F12 without the need
for NVRAM polling.
a) always make the mask-related attributes available in sysfs;
b) use DMI quirks to detect the second-gen firmware;
c) properly report that FN+F3, FN+F4 and FN+F12 are enabled,
and available even on mask-less second-gen firmware;
2. Decouple the issuing of hotkey events towards userspace from
their reception from the firmware. ALSA mixer and brightness
event reporting support will need this feature.
3. Clean up the mess in the hotkey driver a great deal. It is
still very convoluted, and wants a full refactoring into a
proper event API interface, but that is not going to happen
today.
4. Fully reset firmware interface on resume (restore hotkey
mask and status).
5. Stop losing polled events for no good reason when changing the
mask and poll frequencies. We will still lose them when the
hotkey_source_mask is changed, as well as any that happened
between driver suspend and driver resume.
The hotkey subdriver now has the notion of user-space-visible hotkey
event mask, as well as of the set of "hotkey" events the driver needs
(because brightness/volume change reports are not just keypress
reports in most ThinkPad models).
With this rewrite, the ABI level is bumped to 0x020500 should
userspace need to know it is dealing with the updated hotkey
subdriver.

Report KEY_BRIGHTNESSUP and KEY_BRIGHTNESSDOWN input events when the
ThinkPad is in "passive brightness control" mode (because either we or
ACPI video touched _BCL), and ACPI video is not processing these
events by itself.
This happens only on Lenovo ThinkPads with ACPI video support, when
operating with the ACPI video driver in acpi_backlight=vendor mode.
Issuing these events is the right thing to do, and will work around
bugzilla #13368, if userspace is properly configured and actively
handles these events.
For other ThinkPads, and when ACPI video is handling brightness
changes, thinkpad-acpi will continue NOT sending KEY_BRIGHTNESS*
events by default.

Some analysis of the ACPI DSDTs shows that the HKEY pre-enabled mask
is always 0x80c (FN+F3,FN+F4 and FN+F12), which are the hotkeys that
the second gen of HKEY firmware supported (the first gen didn't report
any hotkeys, the second reported these tree hotkeys but had no mask
support, and the third added mask support).
So, this is probably some sort of backwards compatibility with older
versions of the IBM ThinkVantage suite. We have no use for that, and
I know of exactly ZERO users of that attribute, anyway. Start the
process of getting rid of it.

The serio ports on i8042 are not completely isolated; while we provide
enough locking to ensure proper serialization when accessing control
and data registers AUX and KBD ports can still have an effect on each
other on PS/2 protocol level. The most prominent effect is that
issuing a command for the device connected to one port may cause
abort of the command currently executing by the device connected to
another port.
Since i8042 nor serio subsystem are not aware of the details of the
PS/2 protocol (length of the commands and their replies and so on) the
locking should be done on libps2 level by adding special handling when
we see that we are dealing with serio port on i8042.
