Hi,
this patch makes ath9k fail to load, hitting a warning on
compat-wireless-2014-01-23.1/net/wireless/core.c:380, that is
/*
* Combinations with just one interface aren't real,
* however we make an exception for DFS.
*/
if (WARN_ON((c->max_interfaces < 2) && !c->radar_detect_widths))
return -EINVAL;
I think you need to remove the entire configuration if DFS is disabled.
Please find attached a patch that addresses this.
Regards,
M. Braun
