From 73b5b27b7a8a01cf0527ecba5419ef5a44caf27d Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 29 Feb 2016 20:57:29 +0900 Subject: [PATCH] mtd: denali: fix warning when compiled for 64bit system The 64-bit compiler (ex. aarch64) emits "warning: cast from pointer to integer of different size". Make it work with 64bit DMA address while I am here.
