Subject: platform/x86/amd/pmf: Add missing __iomem attribute to policy_base
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bb05226c840ce577d65d91b1fea51d6638c3c896;p=linux.git

platform/x86/amd/pmf: Add missing __iomem attribute to policy_base

The value of policy_base is the return value of a devm_ioremap call,
which returns a __iomem pointer instead of an regular pointer.
Add the missing __iomem attribute.

Compile-tested only.
