USB core: don't match interface descriptors for vendor-specific devices
This patch (as804) makes USB driver matching ignore the interface
class, subclass, and protocol if the device class is Vendor Specific.
Drivers can override this policy by specifying a Vendor ID as part
of the match; then vendor-specific matches are allowed.
Linus Walleij has reported a problem this patch fixes. When a
particular mass-storage device is switched from mass-storage mode to
Media Transfer Protocol, the interface class remains set to mass-storage
and usb-storage binds to it erroneously, even though the device class
changes to Vendor-Specific.
This may cause a problem for some drivers until their match records can
be updated to include Vendor IDs. But if it does, then those records
were broken to begin with.
