usb_control_msg initiates (and waits for completion of) a dma transfer using
the supplied buffer. That buffer thus has to be seperately allocated on
the heap.
In lib/dma_debug.c the function check_for_stack even warns about it:
WARNING: at lib/dma-debug.c:866 check_for_stack
Note: This change is tested to compile only, as I don't have the hardware.

Remote keytables had different names all over the place. Part of the fault
is due to a bad naming when rc subsystem was created, but there were lots
of old names that were still here.
Use a common standard for everything.

This is a big patch, yet trivial. It just move the RC properties
to a separate struct, in order to prepare the dvb-usb drivers to
use rc-core. There's no change on the behavior of the drivers.
With this change, it is possible to have both legacy and rc-core
based code inside the dvb-usb-remote, allowing a gradual migration
to rc-core, driver per driver.

dvb-usb has its own IR handle code. Now that we have a Remote
Controller subsystem, we should start using it. So, remove this
struct, in favor of the similar struct defined at the RC subsystem.
This is a big, but trivial patch. It is a 3 line delect, plus
lots of rename on several dvb-usb files.

In order to be closer to V4L IR implementation, it is needed to replace
u8 custom, data
to:
u16 scan
This allows using non-rc5 mappings, like the 8 bit keycodes used on older
protocols. It will also allow future implementations of rc6 keystrokes
when needed.

The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.
Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.
options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.
With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.

These devices are sold by various companies and chains not involved in
hardware manufacturing business. This particular device owned by
winisch (from irc) had a sticker with text "TCM 234292" on it. This device
was never opened so it is possible that Dposh did not manufacture this
stick. However, the bundled software and their product line points into
that direction. Also thanks to Michael Krufky for spotting this hw
filtering problem and thus avoiding hair loss.
Hardware pid filters and the bundled remote controller are not currently
supported on this device.

Change a 00 to just 0
Detect zero-length I2C messages and return not supported. I think I know
how to send one, but the problem is getting the slave's ack. The only
point of a zero-length message is for probing; too see if the slave will
ack its address. Since we don't know how to get the ack, we can't
support zero-length messages in a useful way, so it's probably best to
just return not supported for them.

The I2C xfer function should now handle more types of I2C transactions
