This patch (as1667) removes an incorrect driver->unbind() call from the net2280 driver. If startup fails, the UDC core takes care of unbinding the gadget driver automatically; the controller driver shouldn't do it too.

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.

with the latest udc_start/udc_stop conversion, too much code was deleted which ended up creating a regression in net2272 and net2280 drivers. To fix the regression we revert one hunk of the original commits. Signed-off-by: NFelipe Balbi <balbi@ti.com>

musb does not use DMA buffer for ep0 but it uses the same giveback function *musb_g_giveback* for all endpoints (*musb_g_ep0_giveback* calls *musb_g_giveback*). So for ep0 case request.dma will be '0' and will result in kernel OOPS if tried to *unmap_dma_buffer* for requests in ep0. Fixed it by doing *unmap_dma_buffer* only for valid DMA addr and checking that musb_ep->dma is valid when unmapping.

Commit 80ab72e1 (usb: musb: omap2430: fix the readiness check in omap_musb_mailbox) made the check incorrect, as we will lose the glue/link status during the normal built-in probe order (twl4030_usb is probed after musb omap2430, but before musb core is ready). As a result, if you boot with USB cable on and load g_ether, the connection does not work as the code thinks the cable is off and the phy gets powered down immediately. This is a major regression in 3.9-rc1. So the proper check should be: exit if _glue is NULL, but if it's initialized we memorize the status, and then check if the musb core is ready.
