Subject: [PATCH] wifi: b43: Stop/wake correct queue in PIO Tx path when QoS is disabled
Git-commit: 77135a38f6c2f950d2306ac3d37cbb407e6243f2
Patch-mainline: v6.9-rc1
References: git-fixes

When QoS is disabled, the queue priority value will not map to the correct
ieee80211 queue since there is only one queue. Stop/wake queue 0 when QoS
is disabled to prevent trying to stop/wake a non-existent queue and failing
to stop/wake the actual queue instantiated.

Fixes: 5100d5ac81b9 ("b43: Add PIO support for PCMCIA devices")
