Subject: [PATCH] scsi: ufs: Remove ufshcd_any_tag_in_use()
Git-commit: bd0b35383193d0d31a0cce3d7c7f7e4be1cc7905
Patch-mainline: v5.17-rc1
References: jsc#PED-818
Use hba->outstanding_reqs instead of ufshcd_any_tag_in_use(). This patch
prepares for removal of the blk_mq_start_request() call from
ufshcd_wait_for_dev_cmd(). blk_mq_tagset_busy_iter() only iterates over
started requests.
