[Kalle Valo]

From: Kalle Valo <quic_kvalo@quicinc.com>

There were few sparse warnings in ath9k. After this patchset ath9k is sparse
warning free.

Please review.

Kalle Valo (3):
  wifi: ath9k: ath9k_set_moredata(): fix sparse warnings
  wifi: ath9k: fix ath9k_use_msi declaration

[PATCH 1/3] wifi: ath9k: ath9k_set_moredata(): fix sparse warnings

[Kalle Valo]

Fix ath9k_set_moredata() to use __le16 with masks and use if statement instead
of multiply operator.

Compile tested only.

[PATCH 2/3] wifi: ath9k: fix ath9k_use_msi declaration

[Kalle Valo]

From: Kalle Valo <quic_kvalo@quicinc.com>

Sparse warns:

drivers/net/wireless/ath/ath9k/init.c:79:5: warning: symbol 'ath9k_use_msi' was not declared. Should it be static?

Move the extern to ath9k.h so that it's visible in init.c.

Compile tested only.

antCtrlChain is an array of __le32 so le32_to_cpu() needs to be used.

Compile tested only.
