From b7047713bda9c21f97494985e96b3bc7df1d0af1 Mon Sep 17 00:00:00 2001 From: "Lad, Prabhakar" Date: Fri, 16 May 2014 10:33:50 -0300 Subject: [PATCH] [media] media: davinci: vpif_capture: use SIMPLE_DEV_PM_OPS this patch uses SIMPLE_DEV_PM_OPS, and drops unneeded members from io_usrs, usrs and makes use of vb2 helepers instead.
