The mutex lock at rc_register_device() was added by commit 08aeb7c9a42a
("[media] rc: add locking to fix register/show race").
It is meant to avoid race issues when trying to open a sysfs file while
the RC register didn't complete.
Adding a lock there causes troubles, as detected by the Kernel lock
debug instrumentation at the Kernel:

In this specific case, some error happened during device init,
causing IR to be disabled.
Let's fix it by adding a var that will tell when the device is
initialized. Any calls before that will return a -EINVAL.
That should prevent the race issues.

Only handle an interrupt if at least one combination of event bit
and related interrupt bit is set.
Previously it was just checked that at least one event bit and
at least one interrupt bit are set.
This fixes issues like the following which was caused by
interrupt sharing:
An interrupt intended for nvt_cir_isr was handled by nvt_cir_wake_isr
first and because status bit CIR_WAKE_IRSTS_IR_PENDING was set
the wake fifo was accidently cleared.
This patch also fixes the bug that nvt_cir_wake_isr returned IRQ_HANDLED
even if it detected that the (shared) interrupt was meant for another
handler.

At least on Zotac CI321 ACPI provides an ioport range for the wake up part
but accessing these ioports has no effect.
Instead the ioport base address is set to another value already
(0xa20 in my case) and accessing this ioport range works.
Therefore set a new ioport base address only if the current ioport base
address is 0 (register reset default).
The need to use the existing base address instead of trying to set
an own one doesn't seem to be limited to this specific device as other
drivers like hwmon/nct6775 do it the same way.
This change was successfully tested on the mentioned device.
And the change should be generic enough to not break the driver for
other chips (however due to lack of appropriate hardware I wasn't
able to test this).

At least on NVT6779D clearing the wake fifo works in learning mode only
(although this condition is not mentioned in the chip spec).
Setting the clear fifo bit has no effect in wake up mode.
Even if clearing the wake fifo should work in wake up mode on other
chips this workaround doesn't hurt.
If needed the caller of nvt_clear_cir_wake_fifo has to take care
of locking.

The FIFO is used for ir_raw_event records, however for some historic
reason the FIFO is used on a per byte basis. IMHO this adds unneeded
complexity. Therefore set up the FIFO for ir_raw_event records.
This also allows to define the FIFO statically as part of
ir_raw_event_ctrl instead of having to allocate the FIFO dynamically.
In addition:
- When writing into the FIFO and it's full return ENOSPC instead of
ENOMEM thus making it easier to tell between "FIFO full" and
"Dynamic memory allocation failed" when the error is propagated to
a higher level.
Also add an error message.
- When reading from the FIFO check whether it's empty.
This is not strictly needed here but kfifo_out is annotated
"must check" anyway.
Successfully tested it with the nuvoton-cir driver.

Many decoders require a trailing space (period without IR illumination)
to be delivered before completing a decode.
Since the gpio-ir-recv driver only delivers events on gpio transitions,
a single IR symbol (caused by a quick touch on an IR remote) will not
be properly decoded without the use of a timer to flush the tail end
state of the IR receiver.
This patch initializes and uses a timer and the timeout field of rcdev
to complete the stream and allow decode.
The timeout can be overridden through the use of the LIRC_SET_REC_TIMEOUT
ioctl.

This driver doesn't claim the IR transmitter to be wakeup source. It
even disables the clock and the IR during suspend-resume cycle.
This patch removes yet another misuse of IRQF_NO_SUSPEND.

This reverts commit 9869da5bacc5c9b865a183bd36c04be76cdd325d.
The current code is not mature enough, the API should allow a single
protocol to be specified. Also, the current code contains heuristics
that will depend on module load order.
