Patch removes err() macros from few usb devices.
It places pr_err in pvrusb2-v4l2.c, dev_err in dabusb and in usbvision
drivers. Beside placing dev_err, patch defines new s2255_dev_err macro
with S2255_DRIVER_NAME in s2255 module.

The name of the pvrusb2 module is not likely to ever change, and there
are plenty of other places where the name is directly coded, so there
is little utility in using a macro to infer the module name here. In
addition, using that macro complicates other uses of the driver
involving older kernels where this macro works differently. Yes I
know for many places we don't have to worry about that. But my
alternative is that I have to build special logic in the pvrusb2
standalone driver to special-case what is otherwise costmetic and that
is just plain nuts for something as trivial as this, especially since
this change does not at all have any compile time or run time impact
on the driver. I'm just removing a nicety that didn't have a lot of
value here to begin with.

Previous v4l-dvb changeset id 4cc8ed11e2e0 changed the pvrusb2-hdw
internal API regarding i2c chip debug register access. However that
change failed to also update the corresponding function comment
describing the API. As driver maintained I never saw a request for an
ack on that change; there probably should have been one especially
since the manner in which this API operates was changed - its
interface is now entangled with a v4l specific struct and I would have
preferred to keep this API clear of moving-target v4l-isms such as
this one if at all possible which is why I had done it the way I did
before. But whatever. This commit at least fixes the comment issue.
