Add suspend resume callbacks to handle the case seen when the bus is suspended by the HOST, and the device opens the port (cat /dev/ttyGS0). Gadget controller (like DWC2) doesn't accept usb requests to be queued in this case (when in L2 state), from the gs_open() call. Error log is printed - configfs-gadget gadget: acm ttyGS0 can't notify serial state, -11 If the HOST resumes (opens) the bus, the port still isn't functional. Use suspend/resume callbacks to monitor the gadget suspended state by using 'suspended' flag. In case the port gets opened (cat /dev/ttyGS0), the I/O stream will be delayed until the bus gets resumed by the HOST.

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.
