CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

This fixes a problem in fintek-cir and nuvoton-cir where the
irq handler would trigger during module load before the rdev member was
set, causing a NULL pointer crash.
It seems this crash is very reproducible (just bombard the receiver with
IR signals during module load), probably because when request_irq is
called, any pending intterupt is handled immediately, before
request_irq returns and rdev can be set.
This same crash was supposed to be fixed by commit
9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR
registration"), but the crash was still observed on the nuvoton-cir
driver.
This commit was tested on nuvoton-cir only.

Before, labels were simply numbered. Now, the labels are named after the
cleanup action they'll perform (first), based on how the winbond-cir
driver does it. This makes the code a bit more clear and makes changes
in the ordering of labels easier to review.
This change is applied only to the rc drivers that do significant
cleanup in their probe functions: ati-remote, ene-ir, fintek-cir,
gpio-ir-recv, ite-cir, nuvoton-cir.
This commit should not change any code, it just renames goto labels.
[mchehab@redhat.com: removed changes at gpio-ir-recv.c, due to
merge conflicts]

The RC_TYPE_* defines are currently used both where a single protocol is
expected and where a bitmap of protocols is expected.
Functions like rc_keydown() and functions which add/remove entries to the
keytable want a single protocol. Future userspace APIs would also
benefit from numeric protocols (rather than bitmap ones). Keytables are
smaller if they can use a small(ish) integer rather than a bitmap.
Other functions or struct members (e.g. allowed_protos,
enabled_protocols, etc) accept multiple protocols and need a bitmap.
Using different types reduces the risk of programmer error. Using a
protocol enum whereever possible also makes for a more future-proof
user-space API as we don't need to worry about a sufficient number of
bits being available (e.g. in structs used for ioctl() calls).
The use of both a number and a corresponding bit is dalso one in e.g.
the input subsystem as well (see all the references to set/clear bit when
changing keytables for example).
This patch separate the different usages in preparation for
upcoming patches.
Where a single protocol is expected, enum rc_type is used; where one or more
protocol(s) are expected, something like u64 is used.
The patch has been rewritten so that the format of the sysfs "protocols"
file is no longer altered (at the loss of some detail). The file itself
should probably be deprecated in the future though.

The TechnoTrend USB IR Receiver sends 125 ISO URBs per second, even when
there is no IR activity. Reduce the number of wake ups from the other
drivers too.
This saves about 0.25ms/s on a 2.4GHz Core 2 according to powertop.

fintek-cir, ite-cir and nuvoton-cir may try to free an I/O region
and/or IRQ handler that was never allocated after a failure in their
respective probe functions. Add and use separate labels on the
failure path so they will do the right cleanup after each possible
point of failure.
Compile-tested only.

The current condition is always true, so everything uses
LOGICAL_DEV_CIR_REV2 (8). It should be that Fintek products
0x0408(F71809) and 0x0804(F71855) use logical device
LOGICAL_DEV_CIR_REV1 (5) and other chip ids use logical device 8.
In other words, this fixes hardware detection for 0x0408 and 0x0804.

An early registration of an ISR was causing a crash to several users (for
example, with the ite-cir driver: http://bugs.launchpad.net/bugs/972723).
The reason was that IRQs were being triggered before a driver
initialisation was completed.
This patch fixes this by moving the invocation to request_irq() and to
request_region() to a later stage on the driver probe function.

There was a missing lock in fintek_suspend. Without the lock, its
possible the system will be in the middle of receiving IR (draining the
RX buffer) when we try to disable CIR interrupts.

This is a new driver for the Fintek LPC SuperIO CIR function, in the
Fintek F71809 chip. Hardware and datasheets were provided by Fintek, so
thanks go to them for supporting this effort.
This driver started out as a copy of the nuvoton-cir driver, and was
then modified as needed for the Fintek chip. The two share many
similaries, though the buffer handling for the Fintek chip is actually
nearly identical to the mceusb buffer handling, so the parser routine is
almost a drop-in copy of the mceusb buffer parser (a candidate for being
abstracted out into shared code at some point).
This initial code drop *only* supports receive, but the hardware does
support transmit as well. I really haven't even started to look at
what's required, but my guess is that its also pretty similar to mceusb.
Most people are probably only really interested in RX anyway though, so
I think its good to get this out there even with only RX.
(Nb: there are also Fintek-made mceusb receivers, which presumably, this
chip shares CIR hardware with).
This hardware can be found on at least Jetway NC98 boards and derivative
systems, and likely others as well. Functionality was tested with an
NC98 development board, in-kernel decode of RC6 (mce), RC5 (hauppauge)
and NEC-ish (tivo) remotes all successful, as was lirc userspace decode
of the RC6 remote.
