Subject[PATCH 1/2 v2] gpio-pch: cleanup __iomem annotation usage
From: Márton Németh <>

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)

[1] A new I/O memory access mechanism (Sep 15, 2004)

[2] Being more anal about iospace accesses (Sep 15, 2004)
