Subject: powerpc/process: Fix sparse address space warnings
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3b35bd48b8a06e02a25af84baba782876b8a6572;p=openwrt%2Fstaging%2Fblogic.git

powerpc/process: Fix sparse address space warnings

This patch fixes the following warnings, which are leftovers
from when __get_user() was replaced by probe_kernel_address().

arch/powerpc/kernel/process.c:1287:22: warning: incorrect type in argument 2 (different address spaces)
arch/powerpc/kernel/process.c:1287:22:    expected void const *src
arch/powerpc/kernel/process.c:1287:22:    got unsigned int [noderef] <asn:1>*<noident>
arch/powerpc/kernel/process.c:1319:21: warning: incorrect type in argument 2 (different address spaces)
arch/powerpc/kernel/process.c:1319:21:    expected void const *src
arch/powerpc/kernel/process.c:1319:21:    got unsigned int [noderef] <asn:1>*<noident>
