The below call stack prevents clk_gating at every IO completion.
We can remove the condition, ufshcd_any_tag_in_use(), since clkgating_work
will check it again.
ufshcd_complete_requests(struct ufs_hba *hba)
ufshcd_transfer_req_compl()
__ufshcd_transfer_req_compl()
__ufshcd_release(hba)
if (ufshcd_any_tag_in_use() == 1)
return;
ufshcd_tmc_handler(hba);
blk_mq_tagset_busy_iter();
