[PATCH 1/2] wifi: ath9k: cleanup struct ath_tx_control and ath_tx_prepare()

[Dmitry Antipov]

After switching to mac80211 software queues, pointer to 'struct ath_node'
in 'struct ath_tx_control' is still assigned but not actually used. So drop
it and cleanup related things in 'ath_tx_prepare()'. Compile tested only.

[PATCH 2/2] wifi: ath9k: use unsigned long for activity check timestamp

[Dmitry Antipov]

Since 'rx_active_check_time' of 'struct ath_softc' is in jiffies,
prefer 'unsigned long' over 'u32' to avoid possible truncation in
'ath_hw_rx_inactive_check()'. Found with clang's -Wshorten-64-to-32,
compile tested only.

I don't think cleanup patches should have a Fixes tag. This is not
fixing a user visible issue.

I don't think this should have a Fixes either. Jeff, can you remove
these during commit?
