Subject: [PATCH 4.17 175/220] media: cx231xx: Ignore an i2c mux adapter

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Brad Love <brad@...tdimension.cc>

commit 13a257f8d5a530bd2aa004a067ba1f2b8f5ef76d upstream.

Hauppauge 935C cannot communicate with the si2157
when using the mux adapter returned by the si2168,
so disable it to fix the device.
