Subject: [PATCH] scsi: ufs: qcom: Enable RPM_AUTOSUSPEND for runtime PM
Git-commit: 6f21d9274c779a6425bd5056005bc69b99c956a4
Patch-mainline: v5.19-rc1
References: jsc#PED-1183

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.
