From: Olof Johansson Date: Thu, 12 Sep 2013 04:27:53 +0000 (-0700) Subject: serial: imx: Change cast to handle 64-bit resource_size_t X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=61c416c2613c238b98e5297034ef50c64690e71d;p=karo-tx-linux.git serial: imx: Change cast to handle 64-bit resource_size_t This resolves a warning where resource_size_t is larger than void *: drivers/tty/serial/imx.c:1542:6: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] Since iomem_base is a void *, casting to unsigned long is safe. It's unclear to me that this comparison is truly needed, but it's there on several other drivers as well.
