Thanks Jun.

I'm going to send one more version, and fix the description of the
struct usb_role_switch_desc like you proposed.

Since the fix will only add one comment line to the code, I'm going to
take the liberty to add your Reviewed-by and Tested-by tags this
time (I don't usually like to carry them to new versions of patches).
I'll do the same with the others.


thanks,
