stable inclusion

commit 36a6e8aeae4a41767bb59f56b100c8cc9ffae2cb
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBNEPJ

--------------------------------

[ Upstream commit b8f7bbd1f4ecff6d6277b8c454f62bb0a1c6dbe4 ]

When removing a genpd we don't clean up the genpd->dev correctly. Let's add
the missing put_device() in genpd_free_data() to fix this.
