Date: Wed, 11 Sep 2013 21:27:53 -0700 From: Olof Johansson <olof@...om.net> To: gregkh@...uxfoundation.org Cc: linux-kernel@...r.kernel.org, linux-serial@...r.kernel.org, Olof Johansson <olof@...om.net> Subject: [PATCH] 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.
