Commit Message

Po-Wen Kao Sept. 29, 2021, 7 a.m. UTC
TM command issued by ufshcd_issue_tm_cmd() inevitably timeout since
interrupt handler iterates wrong request list for completion.

The issue is fixed by iterating static_rqs instead of rqs to find
requests with new interface blk_mq_drv_tagset_busy_iter().
