6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: liuderong <liuderong@xxxxxxxx>
commit f103396ae31851d00b561ff9f8a32a441953ff8b upstream.
lrbp->compl_time_stamp_local_clock is set to zero after sending a sqe
but it is not updated after completing a cqe. Thus the printed
information in ufshcd_print_tr() will always be zero.
Update lrbp->cmpl_time_stamp_local_clock after completing a cqe.
Log sample:
ufshcd-qcom 1d84000.ufshc: UPIU[8] - issue time 8750227249 us
ufshcd-qcom 1d84000.ufshc: UPIU[8] - complete time 0 us
