USB-serial fixes for v4.5-rc2

Browse source 
Here are two fixes of crashes in the visor driver that could be
 triggered using bad (malicious) descriptors, a fix for two memory leaks
 in the new mxu11x0 driver, and an interface-blacklist fix for the option
 driver.
 
 Included are also some new device ids.
