I like the sound of the device match list but I don't know what you

mean.

Is there a driver or other reference you could point me at that provides
additional info?

Depends on what the discriminator is. If problems happen with
a particular ASIC revisions driver needs to read the revision
out and make a match. If it's product by product you can use
struct usb_device_id :: driver_info to attach metadata per
device ID. If it's related to the platform things like DMI
matching are sometimes used. I have very limited experience
with Android / embedded ARM so not sure what would work there.

Thanks. Based on that I will remove this change from the patch set and
discuss again with the driver maintainer.
