[PATCH] bluetooth: btintel_pcie: nonsense error recording in irq

[PATCH] bluetooth: btintel_pcie: nonsense error recording in irq

[Oliver Neukum]

Either you return an error or you ignore it.
Recording it but then overwriting it makes no sense.

Dear Oliver,


Thank you for the patch. I have two minor comments. Could you please 
word the summary as a statement by adding a verb (in imperative mood). 
Maybe:

 > Fix nonsense …

or

 > Remove unused `ret` assignment

It’d be great if you added a Fixes: tag.
