From 1399c5b02c568700ba50ce1ec19c12e71b25c73d Mon Sep 17 00:00:00 2001 From: Alim Akhtar Date: Sun, 6 May 2018 15:44:15 +0530 Subject: scsi: ufs: add quirk to fix mishandling utrlclr/utmrlclr In the right behavior, setting the bit to '0' indicates clear and '1' indicates no change. If host controller handles this the other way, UFSHCI_QUIRK_BROKEN_REQ_LIST_CLR can be used.
