From 4fcfeca833c48e8cb899ae9cff31de481ae52ca2 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Wed, 25 Mar 2015 19:57:33 -0300 Subject: [PATCH] [media] omap3isp: Replace mmio_base_phys array with the histogram block base Only the histogram sub-block driver uses the physical address. Do not store it for other sub-blocks.
