commit48ed32482cupstream. Since commitfc274c1e99("USB: gadget: Add a new bus for gadgets"), the gadget devices are proper driver core devices, which caused each device to request pinmux settings: aspeed_vhub 1e6a0000.usb-vhub: Initialized virtual hub in USB2 mode aspeed-g5-pinctrl 1e6e2080.pinctrl: pin A7 already requested by 1e6a0000.usb-vhub; cannot claim for gadget.0 aspeed-g5-pinctrl 1e6e2080.pinctrl: pin-232 (gadget.0) status -22 aspeed-g5-pinctrl 1e6e2080.pinctrl: could not request pin 232 (A7) from group USB2AD on device aspeed-g5-pinctrl g_mass_storage gadget.0: Error applying setting, reverse things back The vhub driver has already claimed the pins, so prevent the gadgets from requesting them too by setting the magic of_node_reused flag. This causes the driver core to skip the mux request.

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.
