From 92cf8c285a1f3c5600bdbd6a9af4255db5331eee Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Wed, 4 May 2022 14:12:12 +0530 Subject: [PATCH] UPSTREAM: scsi: ufs: qcom: Enable RPM_AUTOSUSPEND for runtime PM In order to allow the block devices to enter autosuspend mode during runtime, thereby allowing the ufshcd host driver to also runtime suspend, let's make use of the RPM_AUTOSUSPEND flag. Without this flag, userspace needs to enable the autosuspend feature of the block devices through sysfs.
