From 0799c2d6f42db2b275b6479035f5b7a30ef4ee39 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 15 Jan 2015 11:54:28 +0100 Subject: [PATCH] net: sh_eth: Use u32 for 32-bit register data Replace "unsigned long" by "u32" when handling 32-bit register data. A.o., this saves 11 * 36 bytes in the static sh_eth_cpu_data structures when compiling for 64-bit. Signed-off-by: Geert Uytterhoeven Signed-off-by: David S.
