If anyone has any objections, please let me know. ------------------ From: Michael Wyraz [ Upstream commit 87c56085bcdfec305f5c350fe1c58a62a7f65843 ] The ASR modem used in the Tuoshi LT22M exposes an RNDIS function on interfaces 0 and 1, a diagnostic port on interface 2, and AT ports on interfaces 3 and 4. Match only the vendor-specific serial interfaces so option does not bind to the RNDIS function.
