ath9k channel table for 2Ghz does not seems to initialize the 'band'
parameter.Though it does not seems to cause any visible issue it looks
odd when we initialize the 'band' parameter for 5Ghz channel table while
not so for 2Ghz.

When rfkill is enabled, ath9k_hw unnecessarily configured the baseband to
turn off based on GPIO input, however that code was hardcoded to GPIO 0
instead of ah->rfkill_gpio.
Since ath9k uses software rfkill anyway, this code is completely unnecessary
and should be removed in case anything else ever uses GPIO 0.

To improve aggregation length, there should not be more than two fully formed
A-MPDU frames in the hardware queue. To ensure this, the code checks the tx
queue length before forming new A-MPDUs. This can reduce the throughput (or
maybe even starve out A-MPDU traffic) when too many non-aggregated frames are
in the queue.
Fix this by keeping track of pending A-MPDU frames (even when they're sent out
as single frames), but exclude rate control probing frames to improve
performance.

All rt2x00 drivers except rt2800pci call ieee80211_tx_status() from
a workqueue, which causes "NOHZ: local_softirq_pending 08" messages.
To fix it, add ieee80211_tx_status_ni() similar to ieee80211_rx_ni()
which can be called from process context, and call it from
rt2x00lib_txdone(). For the rt2800pci special case a driver
flag is introduced.

Its possible for the call to read rx timeout from the hardware to fail,
in which case we end up with a bogus rx timeout value. Set a default one
when filling in the rc struct, and we'll just overwrite it later w/the
value from hardware, but if that read fails, we've at least got a sane
rx timeout value to work with (1000ms is the default value I've seen
returned on most if not all mceusb hardware).

As it turns out, somewhere along the way, we managed to invert the
meaning of the tx_mask_inverted flag. Looking back over the old lirc
driver, tx_mask_inverted was set to 0 if the device was in tx_mask_list.
Now we have a tx_mask_inverted flag set to 1 for all the devices that
were in the list, and set tx_mask_inverted to that flag value, which is
actually the opposite of what we used to set, causing set_tx_mask to use
the wrong mask setting option. Since there seem to be more devices with
inverted masks than not (using the original device as the baseline for
inverted vs. normal), lets just call the ones currently marked as
inverted normal instead, and flip the if/else actions that key off of
the inverted flag.
Note: the problem only cropped up if a call to set_tx_mask was made, if
no mask was set, the device would work just fine, which is why this
managed to slip though w/o getting noticed until now.
Tested successfully by myself and Dennis Gilmore.

This makes several changes but they're in one function and sort of
related:
"buf" was leaked on error. The leak if we try to read an invalid
length is the main concern because it could be triggered over and
over.
If the copy_to_user() failed, then the original code returned the
number of bytes remaining. read() is supposed to be the opposite way,
where we return the number of bytes copied. I changed it to just return
-EFAULT on errors.
Also I changed the debug output from "-EFAULT" to just "<fail>" because
it isn't -EFAULT necessarily. And since we go though that path if the
length is invalid now, there was another debug print that I removed.

When trying to create persistent device names for mceusb and streamzap
devices, I noticed that their respective drivers are not creating the rc
device as a child of the USB device. Rather it creates it as virtual
device. As a result, udev cannot use the USB device information to
create persistent device names for event and lirc devices associated
with the rc device. Not having persistent device names makes it more
difficult to make use of the devices in userspace as their names can
change.

There are cases where we get an ending space, and our trailing timeout
space then gets sent right after it, which breaks repeat, at least for
lirc userspace decoding. Merge the two spaces by way of using
ir_raw_event_store_filter, set a timeout value, and we're back to good.
Successfully tested with streamzap and windows mce remotes.

Something I failed to notice while testing the mceusb RLE buffer
decoding simplification patches was that we were getting an extra event
from the previously pressed key.
As was pointed out to me on irc by Maxim, this is actually due to using
ir_raw_event_store_with_filter without having set up a timeout value.
The hardware has a timeout value we're now reading and storing, which
properly enables the transition to idle in the raw event storage
process, and makes IR decode behave correctly w/o keybounce.
Also remove no-longer-used ir_raw_event struct from mceusb_dev struct
and add as-yet-unused enable flags for carrier reports and learning
mode, which I'll hopefully start wiring up sooner than later. While
looking into that, found evidence that 0x9f 0x15 responses are only
non-zero when the short-range learning sensor is used, so correct the
debug spew message, and then suppress it when using the standard
long-range sensor.

If we pass in an offset, we shouldn't skip 2 bytes. And the first-gen
hardware generates a constant stream of interrupts, always with two
header bytes, and if there's been no IR, with nothing else. Bail from

buffer delivered to us.

We were storing a bunch of spaces at the end of each signal, rather than
a single long space. The in-kernel decoders were actually okay with
this, but lirc isn't. As suggested by David Härdeman, switch to storing
samples using ir_raw_event_store_with_filter, which auto-merges the
consecutive space samples for us. This also allows us to bypass having
to store rawir samples in our device struct, further simplifying the
buffer parsing state machine. Both in-kernel decoders and lirc are happy
again with this change.
Also included in this patch is proper parsing of 0x9f 0x01 commands, the
removal of some magic number usage and some printk spew fixups.

Rather than waiting for trigger bits, the formula for which was slightly
messy, and apparently, not actually 100% complete for some remotes, just
call ir_raw_event_handle whenever we finish parsing a chunk of data from
the rx fifo, similar to mceusb, as well as whenever we see an 'end of
signal data' 0x80 packet.

Today, userspace sets up an input device based on the data it emits.
This is not always enough; a tablet and a touchscreen may emit exactly
the same data, for instance, but the former should be set up with a
pointer whereas the latter does not need to. Recently, a new type of
touchpad has emerged where the buttons are under the pad, which
changes logic without changing the emitted data. This patch introduces
a new ioctl, EVIOCGPROP, which enables user access to a set of device
properties useful during setup. The properties are given as a bitmap
in the same fashion as the event types, and are also made available
via sysfs, uevent and /proc/bus/input/devices.
