Instead of only two frequencies, if OPP V2 is used, the UFS devfreq clock scaling may scale the clock among multiple frequencies. In the case of scaling up, the devfreq may decide to scale the clock to an intermediate freq based on load, but the clock scale up pre change operation uses settings for the max clock freq unconditionally. Fix it by passing the target_freq to clock scale up pre change so that the correct settings for the target_freq can be used. In the case of scaling down, the clock scale down post change operation is doing fine, because it reads the actual clock rate to tell freq, but to keep symmetry with clock scale up pre change operation, just use the target_freq instead of reading clock rate.

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 reStructuredText 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.
