Date: Fri, 5 Jun 2009 04:04:19 -0400 From: Mike Frysinger <vapier@...too.org> To: linux-kernel@...r.kernel.org Cc: uclinux-dist-devel@...ckfin.uclinux.org, Bryan Wu <cooloney@...nel.org> Subject: [PATCH 10/62] Blackfin: fix warnings with I/O port macros The I/O port functions take ints, so we need to cast them up before passing to our read/write funcs to avoid ugly messes of warnings.
