From f3c6abcab5e729f208a28ca18a46360247c7713f Mon Sep 17 00:00:00 2001 From: Olli Salonen Date: Tue, 16 Feb 2016 15:53:45 -0200 Subject: [media] dw2102: convert TechnoTrend S2-4600 to use I2C binding for demod Convert the TT S2-4600 USB tuner to use the I2C binding for attaching the demodulator instead of the old m88ds3103_attach method.
