If the 'driver_initiated' function argument to
__cfg80211_stop_sched_scan() is not 0 then we'll return an
uninitialized 'ret' from the function.

'err'. I also dislike the initialisation, can we just replace the
"return err;" at the end of the function with "return 0;" instead?

Luckily we were never using the return value when passing
driver_initiate =- false.

And I agree with you, there's no use to return err at the end.  Better
to simply return 0.

Luca, should it maybe be return -ENOENT anyway in the !sched_scan_req
case?

We could do that.  I had just thought that stopping a scan that is not
running would just be a NOP, but if you prefer to return an error in
that case, I can do it.
