I'll NAK this ... the trigger type is actually a bit problematic,
it hasn't previously been maintained *anywhere* except possibly as
platform-specific code.  And if it were maintained, desc->status
would be the right place:  the flags for each action would otherwise
need to be updated.

However, given recent cleanups in handling of genirq triggering
I think it's time for me to submit a patch to correct that little
oversight.
