From 1d3ff76759b70e201e6b379c37ac106c487ff506 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Fri, 14 Sep 2012 00:33:48 +0000 Subject: [PATCH] i825xx: znet: fix compiler warnings when building a 64-bit kernel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When building 64-bit kernel with this driver we get following warnings from the compiler: drivers/net/ethernet/i825xx/znet.c: In function ‘hardware_init’: drivers/net/ethernet/i825xx/znet.c:863:29: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] drivers/net/ethernet/i825xx/znet.c:870:29: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] Fix these by calling isa_virt_to_bus() before passing the pointers to set_dma_addr().
