From: Devin Heitmueller Date: Wed, 19 Apr 2017 23:13:45 +0000 (-0300) Subject: [media] au8522: don't touch i2c master registers on au8522 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bb750c7b4cecd6c9d12f41cb71e301141bad8835;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [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.
