From 0d9e301b10422f0c04952d7f3128f2e3ac9b5873 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Wed, 8 Feb 2017 06:53:48 -0200 Subject: [PATCH] [media] s5p-mfc: Replace bank1/bank2 entries with an array Internal MFC driver device structure contains two entries for keeping addresses of the DMA memory banks. Replace them with the dma_base[] array and use defines for accessing particular banks. This will help to simplify code in the next patches.
