[PATCH V2] Staging: media: bcm2048: style fix - bare use of unsigned

[Derek Robson]

Changed macro to not pass signedness and size as seprate fields.
This is to improve code readablity.

version #1 broke the build because I missunderstood the output of checkpatch.

Not really, it reads just fine as is.  In fact, it forces you to think
about the signed vs. unsigned of the variable and doesn't let you forget
it, which seems to be the intention of the code as-is.

So I would recommend just leaving it alone.

Remember, checkpatch is a hint, you always have to use your brain when
making kernel changes, and always test-build them :)

thanks,
