When doing something based on a robot finding, please take a look at 
the related code and _think_(!) instead of just hitting send button. If 
you'd have done that, you'd have submitted a patch that cleans up the 
other (create) cases too, not just the one which your robot flagged.

I think this is the second time I've said this about the very same code 
construct to somebody which, disappointingly, turns out to be you:

https://lore.kernel.org/platform-driver-x86/2ec499b-c37e-0a9-c163-2a1591b56029@linux.intel.com/

Again I get an incomplete patch into my inbox because the previous review 
did not lead into an updated v2 patch. Please do not submit this patch 
again unless you addressed my review feedback.
