usb: gadget: udc: do not clear gadget driver.bus
commit 30d09b3131f5b1b9d54ad9b7ee171a45e21362b3 upstream.
Before the commit fc274c1e9973 ("USB: gadget: Add a new bus for gadgets")
gadget driver.bus was unused. For whatever reason, many UDC drivers set
this field explicitly to NULL in udc_start(). With the newly added gadget
bus, doing this will crash the driver during the attach.
The problem was first reported, fixed and tested with OMAP UDC and g_ether.
Other drivers are changed based on code analysis only.
