Subject: [PATCH] Generic: Move __user cast into probe_kernel_address
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2fff0a48416af891dce38fd425246e337831e0bb;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] Generic: Move __user cast into probe_kernel_address

Caller of probe_kernel_address shouldn't need to know that
pka is internally implemented with __get_user. So move the
__user cast into pka.
