[PATCH 3/3] scsi: hisi_sas: Use non-atomic bitmap functions when possible
From: Christophe JAILLET
Date: Fri Nov 26 2021 - 16:20:56 EST
All uses of the 'hisi_hba->slot_index_tags' bitmap are protected with the
'hisi_hba->lock' spinlock.
So prefer the non-atomic '__[set|clear]_bit()' functions to save a few
cycles.
