[alsa-devel] [PATCH 0/5] Fix poll error returns

[Charles Keepax]

We return negative values from the file_operations poll callback
in a few places, this callback returns an unsigned int and is
expected to only return the poll specific flags. This series
fixes up these issues and makes a couple of small tidy ups to the
code around the edges of those functions.

I noticed this issue whilst doing some additional testing on my
propagation of compressed stream error series, but I decided to
push these up separately as it is worth getting the fixes in
now and not tying them up with that patch chain which is taking
longer to get merged.  Also I included the first patch of that
chain (Replace complex if statement with switch) because it is a
trivial tidy up and might as well get merged now as well.

Thanks,
Charles
