Subject: [PATCH net-next 2/8] wifi: ath9k: silence array-bounds warning on GCC 12

From: Jakub Kicinski <[email-masked]>

GCC 12 says:

drivers/net/wireless/ath/ath9k/mac.c: In function ‘ath9k_hw_resettxqueue’:
drivers/net/wireless/ath/ath9k/mac.c:373:22: warning: array subscript 32 is above array bounds of ‘struct ath9k_tx_queue_info[10]’ [-Warray-bounds]
  373 |         qi = &ah->txq[q];
      |               ~~~~~~~^~~

I don't know where it got the 32 from, relegate the warning to W=1+.
