If userspace is suspended until after devices are resumed, then, in a hand-wavy argument, I don't believe ->stop() could be called. Adding a flag to ath5k_init to make sure we do everything in the mutex would certainly ensure that there's no issues. On the other hand, I don't want to cruft up the code too much since we know at some point mac80211 is going to take down the interfaces in its suspend/resume callbacks, at which time the flags can probably get tossed. -- Bob Copeland %% www.bobcopeland.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
