From d4471deceba46ea6fd60f7fa5e8da3fb72bbbe44 Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Tue, 21 Oct 2014 12:07:00 -0300 Subject: [PATCH] [media] si4713: switch to devm regulator API This switches back to the normal regulator API (but use managed variant) in preparation for device tree support.
