commit c0e129dafce2e2cbf6e4a5131979eb99131e7284
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6CQ

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=c0e129dafce2e2cbf6e4a5131979eb99131e7284

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

commit 87d83b96 upstream.

Drop the leftover pm_runtime_disable() calls from the late probe error
paths that would, for example, prevent runtime PM from being reenabled
after a probe deferral.
