This code does: spin_unlock_irq(&udc->ud.lock); spin_unlock_irqrestore(&udc->lock, flags); which does not make sense. In theory, the first unlock could enable IRQs and then the second _irqrestore could disable them again. There would be a brief momemt where IRQs were enabled improperly. In real life, however, this function is always called with IRQs enabled and the bug does not affect runtime.

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.
