6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jinjie Ruan <ruanjinjie@xxxxxxxxxx>
commit 316e74500d1c6589cba28cebe2864a0bceeb2396 upstream.
It is not valid to call pm_runtime_set_suspended() for devices
with runtime PM enabled because it returns -EAGAIN if it is enabled
already and working. So, call pm_runtime_disable() before to fix it.
