Subject: mt76: remove unnecessary annotations
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5da612090d9a7b1481b7587b3b1deede30a11baf;p=linux.git

mt76: remove unnecessary annotations

Sparse report warnings at mt76_tx_status_unlock() and mt76_tx_status_lock()

warning: context imbalance in mt76_tx_status_lock() - wrong count at exit
warning: context imbalance in mt76_tx_status_unlock() - unexpected unlock

The root cause is the additional __acquire(&dev->status_list.lock)
and __release(&dev->status_list.unlock) called
 from inside mt76_tx_status_lock() and mt76_tx_status_unlock().

Remove __acquire(&dev->status_list.lock) annotation
Remove __releases(&dev->status_list.unlock)
Correct &dev->status_list.unlock to &dev->status_list.lock
	-unlock not defined in the sk_buff_head struct
