3.6.11.2 stable review patch. If anyone has any objections, please let me know. ------------------ From: Alan Stern [ Upstream commit 511f3c5326eabe1ece35202a404c24c0aeacc246 ] This patch (as1666) fixes a regression in the UDC core. The core takes care of unbinding gadget drivers, and it does the unbinding before telling the UDC driver to turn off the controller hardware. When the call to the udc_stop callback is made, the gadget no longer has a driver. The callback routine should not be invoked with a pointer to the old driver; doing so can cause problems (such as use-after-free accesses in net2280). This patch should be applied, with appropriate context changes, to all the stable kernels going back to 3.1.
