The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >>From 391e6dcb37857d5659b53def2f41e2f56850d33c Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 18 Nov 2015 17:06:00 -0600 Subject: usb: gadget: pxa27x: fix suspend callback pxa27x disconnects pullups on suspend but doesn't notify the gadget driver about it, so gadget driver can't disable the endpoints it was using. This causes problems on resume because gadget core will think endpoints are still enabled and just ignore the following usb_ep_enable(). Fix this problem by calling gadget_driver->disconnect().
