From 8a97d4c11756ab6bab8582126d0f1b5c00b067ad Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Thu, 3 Jan 2013 11:21:02 -0300 Subject: [media] soc-camera: fix repeated regulator requesting Currently devm_regulator_bulk_get() is called by soc-camera during host driver probing, but regulators are attached to the camera platform device, that is staying, independent whether the host probed successfully or not. This can lead to repeated regulator requesting, if the host driver is re-probed. Move the call to platform device probing to avoid this.
