Vamshi Gajjela 8bf58028d5 scsi: ufs: core: Fix hba->last_dme_cmd_tstamp timestamp updating logic 
commit ab9fd06cb8f0db0854291833fc40c789e43a361f upstream.

The ufshcd_add_delay_before_dme_cmd() always introduces a delay of
MIN_DELAY_BEFORE_DME_CMDS_US between DME commands even when it's not
required. The delay is added when the UFS host controller supplies the
quirk UFSHCD_QUIRK_DELAY_BEFORE_DME_CMDS.

Fix the logic to update hba->last_dme_cmd_tstamp to ensure subsequent DME
commands have the correct delay in the range of 0 to
MIN_DELAY_BEFORE_DME_CMDS_US.

Update the timestamp at the end of the function to ensure it captures the
latest time after any necessary delay has been applied.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

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.
