After the chipidea driver introduce extcon for id and vbus, it's able
to wakeup from another irq source, in case the system with extcon ID
cable, wakeup from usb ID cable and device removal, the usb device
disconnect irq may come firstly before the extcon notifier while system
resume, so we will get 2 "wakeup" irq, one for usb device disconnect;
and one for extcon ID cable change(real wakeup event), current driver
treat them as 2 successive wakeup irq so can't handle it correctly, then
finally the usb irq can't be enabled. This patch adds a check to bypass
further usb events before controller resume finished to fix it.

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.
