6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold johan@kernel.org
commit 4e31a5d0a9ee672f708fc993c1d5520643f769fd upstream.
Some FTDI devices have the first port reserved for JTAG and have been using a dedicated quirk to prevent binding to it.
As can be inferred directly or indirectly from the commit messages, almost all of these devices are dual port devices which means that the more recently added macro for matching on interface number can be used instead (and some such devices do so already).
This avoids probing interfaces that will never be bound and cleans up the match table somewhat.
Note that the JTAG quirk is kept for quad port devices, which would otherwise require three match entries.
