Refactor xhci_set_cmd_ring_deq() making the code more understandable by using more descriptive constants and separating operations logically. - Remove 'CMD_RING_RSVD_BITS' the macro is misleading, the reserved bits are 5:4, yet the mask is for bits 5:0. - Introduce masks 'CMD_RING_PTR_MASK' and 'CMD_RING_CYCLE' to clearly define the bits for the Command Ring pointer and Command Ring Cycle. - Simplifying the process of setting the command ring address by separating the DMA address calculation and the Command Ring Control register (crcr) updates. - Remove the "// " prefix from trace messages, as it is unnecessary and distracting. Note: In the current implementation, the cycle bit is not cleared before applying the OR operation. Although this hasn't caused issues so far because the bit is '0' before reaching this function, the bit is now cleared before being set to prevent potential future problems and simplify the process.

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.
