If val is a u64, then following:
val *= (u64)1 << 32;
val /= (u64)1 << 32;
should surely be better represented as:
val <<= 32;
val >>= 32;
Especially as, for the division, the compiler might want to actually do a
division:

We'll need to register a sysfs class for the IR devices. As such, the better
is to have the input_register_device()/input_unregister_device() inside
the ir register/unregister functions.
Also, solves a naming problem with V4L ir_input_init() function, that were,
in fact, registering a device.
While here, do a few cleanups at budget-ci IR logic.

This patch fixes the behaviour of the dibusb-i2c-access which was previously changed to avoid accidental EEprom writes:
Now it allow i2c-reads without prepended i2c-writes, but it is still not doing anything in case the EEprom is addressed.

Currently, the IR table is initialized by calling ir_input_init(). However,
this function doesn't return any error code, nor has a function to be called
when de-initializing the IR's.
Change the return argment to integer and make sure that each driver will
handle the error code. Also adds a function to free any resources that may
be allocating there: ir_input_free().

Packet DMA buffers are queued either initially all at once (then, a
queueing failure will cause firedtv to release the DMA context as a
whole) or subsequently one by one as they recycled after use (then a
failure is extremely unlikely). Therefore we can be a little less
cautious when counting at which packet buffer to set the interrupt flag.

The firedtv DVB driver will now work not only on top of the old ieee1394
driver stack but also on the new firewire driver stack.
Alongside to the firedtv-1394.c backend for driver binding and I/O, the
firedtv-fw.c backend is added. Depending on which of the two 1394
stacks is configured, one or the other or both backends will be built
into the firedtv driver.
This has been tested with a DVB-T and a DVB-C box on x86-64 and x86-32
together with a few different controllers (Agere FW323, a NEC chip, TI
TSB82AA2, TSB43AB22/A, VIA VT6306).

The 4 bytes which were referred to as FIREWIRE_HEADER_SIZE are actually
the source packet header from IEC 61883-4 (MPEG2-TS data transmission
