From 17d7265c7582af77357bd31884cef26f9f802313 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Mon, 23 Nov 2009 23:22:15 +0200 Subject: wl1271: fix the inetdev notifier callback return values The wl1271_dev_notify() was returning 0 or -ENODEV, when it should return NOTIFY_* instead. Now we use NOTIFY_DONE when we didn't handle the event or NOTIFY_OK when we have handled it. For inetdev notifications, it doesn't matter whether we use NOTIFY_DONE or NOTIFY_OK, because it ignores the return value of the call to blocking_notifier_call_chain(). But the notify.h header says that NOTIFY_DONE is "Don't care" and NOTIFY_OK is "Suits me", so that seems to be the right way to do it.
