[ Upstream commit defde5a50d91c74e1ce71a7f0bce7fb1ae311d84 ]
The UFSHCI 4.0 specification mandates that there should always be at least
one empty slot in each queue for distinguishing between full and empty
states. Enlarge 'hwq->max_entries' to 'DeviceQueueDepth + 1' to allow
UFSHCI 4.0 controllers to fully utilize MCQ queue slots.

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.
