[PATCH 0/1] video: convert to use new I2C API

From: Wolfram Sang <wsa+renesas@sang-engineering.com>
Date: 2020-03-26 21:10:17

We are deprecating calls which return NULL in favor of new variants which
return an ERR_PTR. Only build tested.

Move away from the deprecated API and return the shiny new ERRPTR where
useful.
