From 3f08b8ba9f5d7ec528a9fc293e76a14c2851e403 Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Fri, 2 Oct 2015 23:26:42 +0530 Subject: [PATCH] mtd: brcmnand: Fix pointer type-cast in brcmnand_write() We should always type-cast pointer to "long" or "unsigned long" because size of pointer is same as machine word size. This will avoid pointer type-cast issues on both 32bit and 64bit systems. This patch fixes pointer type-cast issue in brcmnand_write() as-per above info.
