Subject: [PATCH 006/110] [media] mceusb: improve ir data buffer parser
Switch to a state machine that properly handles all incoming urb data
packets, and reads much cleaner and corrects some minor parsing errors
that were hindering decode on cx231xx/Polaris integrated IR. Also tested
with four different mceusb variants, and works perfectly with all of
them (at least for the rc6a mce remotes).

Subject: [PATCH 007/110] [media] mceusb: add a per-model structure
The previous logic needed duplicate USB table structs, one to store
the list of the devices, and 3 sets of other structs, to store the
quirks list.
With this change, devices that require expecial quirks just need to
have a .driver_info = <quirk entry>.
It also allows adding some extra quirks, like per-model RC tables.
As a bonus, this patch reduced in 10% the data segment size:
text data bss dec hex filename

Subject: [PATCH 104/110] [media] mceusb: fix up reporting of trailing space
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.

V4L/DVB: IR/nuvoton: address all checkpatch.pl issues
The driver was missing KERN_ facilities on a number of printks. The
register dump functions have been updated to use KERN_INFO, so that the
register dump gets logged in syslog (they only run on driver load, and
only when debug is enabled). The buffer dump routine now uses
KERN_DEBUG, as that spew will happen quite frequently (several times
every IR signal), and shouldn't need to be logged.
Also split up the small handful of lines that were just over 80
characaters, and fixed the ioctl.h include.
