From 4986e5c7cd91817d0f58dd15073c9080d47980cf Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Wed, 6 Jun 2012 12:05:01 +0200 Subject: ARM: mm: fix type of the arm_dma_limit global variable arm_dma_limit stores physical address of maximal address accessible by DMA, so the phys_addr_t type makes much more sense for it instead of u32. This patch fixes the following build warning: arch/arm/mm/init.c:380: warning: comparison of distinct pointer types lacks a cast Reported-by: Russell King Signed-off-by: Marek Szyprowski --- arch/arm/mm/init.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/arm/mm/init.c') diff --git a/arch/arm/mm/init.c b/arch/arm/mm/init.c index c21d06c7dd7e..f54d59219764 100644 --- a/arch/arm/mm/init.c +++ b/arch/arm/mm/init.c @@ -212,7 +212,7 @@ EXPORT_SYMBOL(arm_dma_zone_size); * allocations.
