From: Hui Su Date: Fri, 6 Nov 2020 14:47:40 +0000 (+0800) Subject: cgroup/cgroup.c: replace 'of->kn->priv' with of_cft() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5a7b5f32c5aa628841502d19a813c633ff6ecbe4;p=linux.git cgroup/cgroup.c: replace 'of->kn->priv' with of_cft() we have supplied the inline function: of_cft() in cgroup.h. So replace the direct use 'of->kn->priv' with inline func of_cft(), which is more readable.
