remove left-over code or uncomment required condition?
Yes, this can be removed.

test for idr_alloc() success? You have error checks for idr_find() but
not for the _alloc() case.
Yes, error handing is missing in this case, fixed in next version.

this would keep ret = -EINVAL and return it, that seems suspicious since
this doesn't look as an error case?

That's also weird, maybe initialize to zero and return an error code in
error cases, or fix the case APM_CMD_RSP_GET_SPF_STATE above.
this is now fixed by initializing the ret to 0 and setting it in error path.

so all the defaults are errors?
