In an audit of lockdep calls in the driver, there are multiple lockdep checks in successive calling layers. E.g. a routine checks, and then calls a lower routine that also checks, and so on. Calling sequences result in many redundant checks. Refine the code to remove lower-level lockdep checks. Update comments on the lock, correcting a few places where lock object in comment was incorrect.

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.
