In the ufshcd_clear_cmds(), the 2nd parameter would be the bit mask of the command to be cleared in the transfer request door bell register. This bit mask mechanism does not scale well in MCQ mode when the queue depth becomes much greater than 64. Change the 2nd parameter to the function to be the task_tag number of the corresponding bit to be cleared in the door bell register. By doing so, MCQ mode with a large queue depth can reuse this function. Since the behavior of this function is changed from handling multiple commands into a single command, rename ufshcd_clear_cmds() into ufshcd_clear_cmd(). Signed-off-by: Bao D.

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.
