From 812fe6d9426a23ad78055f1fa955acef9bea9a93 Mon Sep 17 00:00:00 2001 From: Hans-Frieder Vogt Date: Sun, 1 Apr 2012 14:11:29 -0300 Subject: [PATCH] [media] af9035: i2c read fix Enable i2c read requests. I2C read fix (necessary e.g. for mxl5007t tuner, because it sends a 2 bytes for a read request, thus msg[0].len != msg[1].len).
