commit b18490138dc69ed83c5cfcdad8789004e67fee8d
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7TH9O

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=b18490138dc69ed83c5cfcdad8789004e67fee8d

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

[ Upstream commit 6049aae5 ]

If an error occurs after a successful pm_genpd_init() call, it should be
undone by a corresponding pm_genpd_remove().

Add the missing call in the error handling path, as already done in the
remove function.
