iwl3945: queue the right work if the scan needs to be aborted
iwl3945's scan_completed calls into the mac80211 stack which triggers a
warn on if there is no scan outstanding.
This can be avoided by not calling scan_completed but abort_scan in
iwl3945_request_scan in the done: branch of the function which is used
as an error out.
The done: branch seems to be an error-out branch, as, for example, if
iwl_is_ready(priv) returns false the done: branch is executed.
NOTE:
I'm not familiar with the driver at all.
I just quickly scanned as a reaction to
https://bugzilla.kernel.org/show_bug.cgi?id=17722
the users of scan_completed in the iwl3945 driver and noted the odd
discrepancy between the comment above this instance and the comment in
mac80211 scan_completed function.
