From e076c92ed6908b0a06ea0d419606a59cae7febe6 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 9 Jul 2011 13:06:12 -0300 Subject: [PATCH] [media] drxk: Convert an #ifdef logic as a new config parameter Instead of using #ifdef I2C_LONG_ADR for some devices, convert it into a parameter. Terratec H5 logs from the original driver seems to need this mode.
