From c3c3f1ae8bab74c99fa211c76b035a41523e83dd Mon Sep 17 00:00:00 2001 From: Matthias Schwarzott Date: Thu, 2 Oct 2014 02:20:59 -0300 Subject: [PATCH] [media] cx231xx: add wrapper to get the i2c_adapter pointer This is a preparation for mapping I2C_1_MUX_1 and I2C_1_MUX_3 later to the seperate muxed i2c adapters. Map mux adapters to I2C_1 for now. Add local variables for i2c_adapters in dvb_init to get line lengths shorter.
