From 2b7a521b121ebc16b9137f07ded7874105c9486a Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 8 May 2012 16:19:34 -0700 Subject: [PATCH] staging: comedi: mite: mite_io_addr and daq_io_addr are void __iomem * The mite_io_addr and daq_io_addr variables in struct mite_struct are both ioremap'ed pci resources and should be void __iomem * not void *. This quiets a lot of sparse warings for the write[lwb],read[lwb] calls in the comedi mite drives like: warning: incorrect type in argument 1 (different address spaces) expected void const volatile [noderef] *addr got void * warning: incorrect type in argument 2 (different address spaces) expected void volatile [noderef] *addr got void * It also exposed some warnings in the mite ni_660x driver where the daq_io_address was getting cast as a void *const.
