From e7ee762cf074b0fd8eec483d0cef8fdbf0d04b81 Mon Sep 17 00:00:00 2001 From: Florian Mickler <florian@mickler.org> Date: Fri, 24 Sep 2010 18:22:01 +0200 Subject: 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.
