Subject: powerpc/numa: Use of_get_next_parent to simplify code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1def37586fb1f3bbbedeaa64bf047595958dfc66;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

powerpc/numa: Use of_get_next_parent to simplify code

of_get_next_parent can be used to simplify the while() loop and
avoid the need of a temp variable.
