commit86762ad4abupstream. During interrupt registration, attach state is checked. If attached, then the Type-C state is updated with typec_set_xxx functions and role switch is set with usb_role_switch_set_role(). If the usb_role_switch parameter is error or null, the function simply returns 0. So, to update usb_role_switch role if a device is attached before the irq is registered, usb_role_switch must be registered before irq registration.

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.
