Subject: [PATCH] ath9k: wake up the chip for TSF reset
If we are in NETWORK SLEEP state, AR_SLP32_TSF_WRITE_STATUS limit
always exceeds in 'ath9k_hw_reset_tsf', because reading of the
AR_SLP3 register always return with the magic 0xdeadbeef value.

Subject: [PATCH 1/2] ath9k: fix race with IEEE80211_CONF_PS checks
There is a small window where the mac80211 changes the IEEE80211_CONF_PS
flag, and then informs the driver about the change. We have a race
condition if we are checking the flag in the same time. Avoid it by
introducing a local variable, and using that instead of checking the
IEEE80211_CONF_PS flag directly.
This fix the problem reported by Luis:
