From e66413faa5b55800ad42a570aad674aed634c5e6 Mon Sep 17 00:00:00 2001 From: Peter Wang Date: Wed, 4 Oct 2023 14:24:54 +0800 Subject: scsi: ufs: core: Remove dev cmd clock scaling busy If a dev command times out, clk_scaling.active_reqs is not decreased which causes abnormal clock scaling. It is complicated to handle different dev command timeout cases in both legacy mode and MCQ mode. Besides, dev cmds are rarely used and the busy time is short. Remove clock scaling busy window for dev cmds like we do for UIC or TM cmds which don't update busy window either.
