We can't use kfree_skb in irq disable context, because spin_lock_irqsave
make sure we are always in irq disable context, use dev_kfree_skb_irq
instead of kfree_skb is better than dev_kfree_skb_any.

ath10k: fix rx_channel during hw reconfigure 2016-06-08T01:18:48+00:00 Rajkumar Manoharan rmanohar@qti.qualcomm.com 2016-04-07T06:41:54+00:00 ffebbb1e6efc11a6ba838001f6156227f9971ea8 commit 1ce8c1484e80010a6e4b9611c65668ff77556f45 upstream. Upon firmware assert, restart work will be triggered so that mac80211 will reconfigure the driver. An issue is reported that after restart work, survey dump data do not contain in-use (SURVEY_INFO_IN_USE) info for operating channel. During reconfigure, since mac80211 already has valid channel context for given radio, channel context iteration return num_chanctx > 0. Hence rx_channel is always NULL. Fix this by assigning channel context to rx_channel when driver restart is in progress.

num_chanctx > 0. Hence rx_channel is always NULL. Fix this by assigning

ath9k: Fix LED polarity for some Mini PCI AR9220 MB92 cards. 2016-06-08T01:18:48+00:00 Vittorio Gambaletta (VittGam) linux-wireless@vittgam.net 2016-04-11T02:48:55+00:00 13ada841daef975e07a5a288f52b1bdd0d25f8ff commit 0f9edcdd88a993914fa1d1dc369b35dc503979db upstream. The Wistron DNMA-92 and Compex WLM200NX have inverted LED polarity (active high instead of active low). The same PCI Subsystem ID is used by both cards, which are based on the same Atheros MB92 design.
