From 08154695076c1aecd2f9bcde79825b45f5ac23b2 Mon Sep 17 00:00:00 2001 From: "Lad, Prabhakar" Date: Fri, 22 Mar 2013 04:53:13 -0300 Subject: [PATCH] [media] media: davinci: vpbe: venc: move the enabling of vpss clocks to driver The vpss clocks were enabled by calling a exported function from a driver in a machine code. calling driver code from platform code is incorrect way. This patch fixes this issue and calls the function from driver code itself.
