6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kamalesh Babulal <kamalesh.babulal@xxxxxxxxxx>
[ Upstream commit d24f05987ce8bf61e62d86fedbe47523dc5c3393 ]
Use css directly instead of dereferencing it from &cgroup->self, while
adding the cgroup v2 cft base and psi files in css_populate_dir(). Both
points to the same css, when css->ss is NULL, this avoids extra deferences
and makes code consistent in usage across the function.
