From: Arnd Bergmann Date: Thu, 8 May 2014 14:56:14 +0000 (+0200) Subject: mtd: onenand: fix build warning for dma type X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=81d46c59550997ae17e441c0327ee92f7ba7dc6f;p=openwrt%2Fstaging%2Fblogic.git mtd: onenand: fix build warning for dma type The samsung onenand driver passes around a dma address token through a void pointer, which is incorrect and leads to warnings like this one: onenand/samsung.c:548:2: warning: passing argument 1 of '__fswab32' makes integer from pointer without a cast [enabled by default] writel(src, base + S5PC110_DMA_SRC_ADDR); ^ This patch makes it use dma_addr_t here, which is more appropriate.
