[PATCH 3.16 146/357] usb: dwc2/gadget: do not call disconnect method in pullup

From: Greg Kroah-Hartman
Date: Fri Oct 03 2014 - 20:40:03 EST


3.16-stable review patch. If anyone has any objections, please let me know.

------------------

From: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>

commit b510df5a36c066da3a188f4ade3404118b63c6de upstream.

This leads to potential spinlock recursion in composite framework, other
udc drivers also don't call it directly from pullup method.
