commit50a318cc9bupstream. The commitd3cb25a121("usb: gadget: udc: fix spin_lock in pch_udc") obviously was not thought through and had made the situation even worse than it was before. Two changes after almost reverted it. but a few leftovers have been left as it. With this revertd3cb25a121completely. While at it, narrow down the scope of unlocked section to prevent potential race when prot_stall is assigned.

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.
