Subject: [PATCH] hostap: Add missing annotations for prism2_bss_list_proc_start() and prism2_bss_list_proc_stop
Git-commit: 1c0e3c73e98dd55bc9551279fed6233997425c23
Patch-mainline: v5.8-rc1
References: jsc#SLE-13430, bsc#1176741

Sparse reports warnings at prism2_bss_list_proc_start() and prism2_bss_list_proc_stop()

Warning: context imbalance in prism2_wds_proc_stop() - unexpected unlock
Warning: context imbalance in prism2_bss_list_proc_start() - wrong count at exit

The root cause is the missing annotations at prism2_bss_list_proc_start()

Add the missing __acquires(&local->lock) annotation
Add the missing __releases(&local->lock) annotation
