[PATCH v6 07/14] media: platform: pxa_camera: make printk consistent

From: Robert Jarzmik
Date: Tue Sep 06 2016 - 05:12:10 EST


Make all print consistent by always using :
- dev_xxx(pcdev_to_dev(pcdev), ....)

This prepares the soc_camera adherence removal by making these call rely
on only pcdev, and not the soc_camera icd structure.
