UPSTREAM: usb: gadget: f_serial: Ensure gserial disconnected during unbind Some UDCs may return an error during pullup disable as part of the unbind path for a USB configuration. This will lead to a scenario where the disable() callback is skipped, whereas the unbind() still occurs. If this happens, the u_serial driver will continue to fail subsequent binds, due to an already existing entry in the ports array. Ensure that gserial_disconnect() is called during the f_serial unbind, so the ports entry is properly cleared.

BEST: Make all of your changes to upstream Linux. If appropriate, backport to the stable releases. These patches will be merged automatically in the corresponding common kernels. If the patch is already in upstream Linux, post a backport of the patch that conforms to the patch requirements below.
EXPORT_SYMBOL_GPL()
require an in-tree modular driver that uses the symbol -- so include the new driver or changes to an existing driver in the same patchset as the export.LESS GOOD: Develop your patches out-of-tree (from an upstream Linux point-of-view). Unless these are fixing an Android-specific bug, these are very unlikely to be accepted unless they have been coordinated with kernel-team@android.com. If you want to proceed, post a patch that conforms to the patch requirements below.
