The former style suggests a modulo arithmetic misuse but
the expression should never be < 0. Even if it does, the
driver will simply loop longer than expected (not that
the remaining parts of the system will necessarily
appreciate it...).
Let's warn the user when something goes wrong and try
to go over it.

The driver version number has not been updated since the driver was
included in the main kernel tree and there is no plan on updating this
in the future either. At this point, the only correct way to refer to
the version is to use the kernel version. The 0.4.4 version is
confusing since there are external version with higher version number
even though they are not actually any newer than the in-tree version.
Let's get rid of the version number in the kernel tree in order to
avoid this kind of confusion.

The vendor driver code suggests that CR47 patching happens on every channel
change for every RF (depending on bit 8 in POD).
Due to a bug in their driver (upper bits of RF_Mode get zeroed out, then
are examined for 1s when setting some other flags), this isn't actually
what happens, and their generic CCK patching routine never takes effect.
Some of their RF configurations do include explicit (duplicated) code
for CR47 patching though. This patch makes zd1211rw match that
behaviour.

This patch adds support for another radio appearing in new devices: the
Ubec UW2453. It's more complicated than the other RF's we support, but
Ubec publish full tech specs so we're able to understand the vendor code
relatively well.
Now that we support UW2453, we also support Atheros' new USB chip: the
AR5007UG. From the little info we have, this appears to be just a
rebranded ZD1211B.
This RF code doesn't work very well -- lots more TX/RX errors than the
other RFs. However, the vendor driver doesn't do any better, so this is
all we can do for now.
