Could pcap_ts->work be still running at this point?

I think it is preferred that .suspend and .resume assigments are
guarded by #ifdef CONFIG_PM, not creating NULL stubs as this will
(theoretically) allow removing .suspend and .resume pointers from
driver stucture when compiling without PM support.

Also try running through checkpatch.pl - there are a few warnings I'd
like to be fixed as well. Otherwise looks pretty good.

Oh, and you need to add your sign-off please. Thanks!
