The intr_idx_lock lock is acquired only in the completion callback of the ->int_in_urb (iowarrior_callback()). There is only one URB that is scheduled / completed so there can't be more than one user of the lock. The comment says that it protects ->intr_idx and the callback is the only place in driver that writes to it. Remove the intr_idx_lock lock because it is superfluous.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
