From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH] staging: amso1100: fix format string for 64-bit phys_addr Date: Mon, 01 Feb 2016 17:34:52 +0100 Message-ID: <2307631.X1DYNXxKPZ@wuerfel> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7Bit Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Doug Ledford , Sean Hefty , Hal Rosenstock Cc: Greg Kroah-Hartman , linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devel-gWbeCf7V1WCQmaza687I9mD2FQJk+8+b@public.gmane.org, linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org List-Id: linux-rdma@vger.kernel.org The amso1100 driver prints a phys_addr_t by casting it to a pointer, which causes a warning when phys_addr_t is 64-bit and pointers are 32-bit: drivers/staging/rdma/amso1100/c2.c: In function 'c2_rx_error': drivers/staging/rdma/amso1100/c2.c:430:4: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] This changes the format string to print the address as a 64-bit number all the time to avoids the warnings. Ideally we would use the %pap format string for phys_addr_t, but that doesn't work here easily as it requires passing a pointer to the address.
