Subject: iwlwifi: change WARN_ON to IWL_WARN in iwl_mac_add_interface
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=4bd530f3ab51c7d656bca29d927a50e5aa87175e;p=deliverable%2Flinux.git

iwlwifi: change WARN_ON to IWL_WARN in iwl_mac_add_interface

We can start restarting firmware or RF kill switch can be turned on
during call to iwl_mac_add_interface(). That are normal working
conditions, so do not print call trace, just print simple message
instead.
