Please use the normal kernel coding style. People read in part by
pattern matching so this is important to ease review and coding style
problems are a big warning sign that the code also has problems with
other, more substantial, understanding of how the kernel is expected to
work.

Why not just directly do this in the switch statement? This appears to
be the only place where we change behaviour so setting a variable at the
top of the function then using it at the bottom doesn't seem to add
anything.
