gpio-pch: cleanup __iomem annotation usage
The __iomem annotation is to be used together with pointers used as iowrite32() parameter. For more details see [1] and [2]. This patch will remove the following sparse warnings ("make C=1"): * warning: incorrect type in assignment (different address spaces) * warning: incorrect type in argument 1 (different address spaces) * warning: incorrect type in argument 2 (different address spaces) References: [1] A new I/O memory access mechanism (Sep 15, 2004) http://lwn.net/Articles/102232/ [2] Being more anal about iospace accesses (Sep 15, 2004) http://lwn.net/Articles/102240/ Signed-off-by: Márton Németh <nm127@freemail.hu> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
