From bb750c7b4cecd6c9d12f41cb71e301141bad8835 Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Wed, 19 Apr 2017 20:13:45 -0300 Subject: [PATCH] [media] au8522: don't touch i2c master registers on au8522 Some stray lines got inserted into the driver when I reverse engineered the I2C traffic (at the time I didn't know what the registers did). It turns up these registers muck with the onboard I2C master, which we don't use since we instead use the I2C gate. Remove the lines which can actually interfere with the operation of the bus.
