Subject: [media] cx231xx: don't return error on success

From: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

commit 1871d718a9db649b70f0929d2778dc01bc49b286 upstream.

The cx231xx_set_agc_analog_digital_mux_select() callers
expect it to return 0 or an error. Returning a positive value
makes the first attempt to switch between analog/digital to fail.
