From 61e220adf68553b6e5f61b9339ce9d3e92df27cb Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Wed, 9 Aug 2017 05:37:30 -0400 Subject: [PATCH] media: i2c: adv748x: Export I2C device table entries as module aliases The I2C core always reports a MODALIAS of the form i2c: even if the device was registered via OF, and the driver is only exporting the OF ID table entries as module aliases. So if the driver is built as module, autoload won't work since udev/kmod won't be able to match the registered OF device with its driver module.
