Immediately after successful UFS link startup, UFS link power mode would be in PWM-G1, 1-lane, SLOW-AUTO mode. But currently we are doing few of the DME local/peer attributes access before setting the "hba->pwr_info" to default power mode. If we are doing link startup as part of error recovery then old power mode might be set to FAST mode and doing DME peer access (after link startup but before updating "hba->pwr_info" to default power mode) unintentionally tries to switch from FAST to FAST_AUTO mode (if UFSHCD_QUIRK_DME_PEER_ACCESS_AUTO_MODE quirk is enabled). Above issue is fixed by setting the default power mode immediately after successful link startup.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
