Subject[PATCH 5.4 013/135] USB: misc: iowarrior: add support for the 28 and 28L devices
Date
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 5f6f8da2d7b5a431d3f391d0d73ace8edfb42af7 upstream.

Add new device ids for the 28 and 28L devices. These have 4 interfaces
instead of 2, but the driver binds the same, so the driver changes are
minimal.
