Introduce an auto-cleanup macro for the temporary shutdown locks for USB-audio, and replace the manual lock/unlock pairs with it. Namely, the former err = snd_usb_lock_shutdown(chip); if (err < 0) return err; .... snd_usb_unlock_shutdown(chip); is replaced with CLASS(snd_usb_lock, pm)(chip); if (pm.err < 0) return pm.err; .... with the automatic unlocking.

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.
