The fusb302 irq handler has been carefully optimized by Hans de Goede in commit207338ec5a("usb: typec: fusb302: Improve suspend/resume handling"). A recent 'fix' undid most of that work to avoid a virtio-gpio driver bug. This reverts the incorrect fix, since it is of very low quality. It reverts the quirks from Hans change (and thus reintroduces the problems fixed by Hans) while keeping the overhead from the original change. The proper fix to support using fusb302 with an interrupt line provided by virtio-gpio must be implemented in the virtio driver instead, which should support disabling the IRQ from the fusb302 interrupt routine.

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.
