There are couple places where we check unsigned values for negative.  I
changed ->gpin_nr to signed because in gpio_ir_recv_probe() we do:
        if (pdata->gpio_nr < 0)
                return -EINVAL;
I also change gval to a signed int in gpio_ir_recv_irq() because that's
the type that gpio_get_value_cansleep() returns and we test for negative
returns.

The raw Sony IR decoder decodes 15bit messages slightly incorrectly.
To decode the function number, it shifts the bits right by 7 so that the
function is in bits 7:1, masks with 0xFD (0b11111101), and does an 8 bit
reverse so it ends up in bits 6:0. The mask should be 0xFE to correspond
with bits 7:1 (0b11111110).

The old mask had the effect of dropping the MSB of the function number
from bit 6, and leaving the LSB of the device number in bit 7.

Raw IR events are passed to the raw event thread through a kfifo. The
size of the event struct is 12 bytes, and space for 512 events is
reserved in the kfifo (6144 bytes), however this is rounded down to 4096
bytes (the next power of 2) by __kfifo_alloc().

4096 bytes is not divisible by 12 therefore if the fifo fills up a third
of a record will be written in the end of the kfifo by
ir_raw_event_store() because the recsize of the fifo is 0 (it doesn't
have records). When this is read by ir_raw_event_thread() a corrupted or
partial record will be read, and in the case of a partial record the
BUG_ON(retval != sizeof(ev)) gets hit too.

According to samples/kfifo/record-example.c struct kfifo_rec_ptr_1 can
handle records of a length between 0 and 255 bytes, so change struct
ir_raw_event_ctrl to use that instead of struct kfifo.

This patch is just a minor update to one titled "imon: Input from ffdc
device type ignored" from Corinna Vinschen. An earlier patch to prevent
an oops when we got early callbacks also has the nasty side-effect of
wedging imon hardware, as we don't acknowledge the urb. Rework the check
slightly here to bypass processing the packet, as the driver isn't yet
fully initialized, but still acknowlege the urb and submit a new rx_urb.
Do this for both interfaces -- irrelevant for ffdc hardware, but
relevant for newer hardware, though newer hardware doesn't spew the
constant stream of data as soon as the hardware is initialized like the
older ffdc devices, so they'd be less likely to trigger this anyway...

Tested with both an ffdc device and an 0042 device.

The ati_remote driver currently uses 2-byte scancodes. However, one of
those bytes is actually a checksum and therefore shouldn't be considered
as part of the scancode.

Fix the driver to only use the actual data byte as a scancode and to
check the checksum itself. Update the bundled keymaps accordingly.

Since ati_remote was only migrated to the rc subsystem for 3.2, the
previous scancodes weren't emitted on any stable kernel.

This patch to the IR RC6 decoder adds support for variable length
mode-6A frames which can range in size from 8 to 128 bits.  Please refer
to the following link for a detailed explanation or RC6 frames:
http://slydiman.narod.ru/scr/kb/rc6.htm

This change removes the assumption that frames are fixed length
(currently either 24 or 32 data bits) and actually counts the number of
bits until an end of frame marker is seen.

The imon devices have either 1 or 2 usb interfaces on them, each wired
up to its own urb callback. The interface 0 urb callback is wired up
before the imon context's rc_dev pointer is filled in, which is
necessary for imon 0xffdc device auto-detection to work properly, but we
need to make sure we don't actually run the callback routines until
we've entirely filled in the necessary bits for each given interface,
lest we wind up oopsing. Technically, any imon device could have hit
this, but the issue is exacerbated on the 0xffdc devices, which send a
constant stream of interrupts, even when they have no valid key data.

ir_raw_event_store_with_filter() already merges back to back like
samples types for us. This should also fix a regression introduced late
in 3.0 that related to a timeout change, which actually becomes correct
when coupled with this change. Tested with RC6 and RC5 on my own
nuvoton-cir hardware atop vanilla 3.0.0, after verifying quirky
behavior in 3.0 due to the timeout change.
