We see issue with this patch series. For our device running at SSP, the
device couldn't recover from a port reset and remained in eSS.Inactive
state.
This patch series is already in Greg's usb-testing. Please review and
help fix it.
We can see the failure once the patch "usb: gadget: configfs: Add a
specific configFS reset callback" is introduced.
