From ed6e52829c113ca18f042ac55cc77b1b90745eab Mon Sep 17 00:00:00 2001 From: "Andrew M. Bishop" Date: Tue, 21 Aug 2007 19:08:56 +0100 Subject: [PATCH] USB: ftdi_sio: Handle FT232RL devices like FT232BM devices Handle the FT232RL device type in exactly the same way as FT232BM devices (FT232RL detection was added around kernel 2.6.20 but not code for handling it).
