6.6-stable review patch. If anyone has any objections, please let me know.

From: Sumit Gupta <sumitg@xxxxxxxxxx>
[ Upstream commit bae8222a6c291dbe58c908dab5c2abd3a75d0d63 ]
Fix the warning due to missing dev_pm_opp_put() call and hence
wrong refcount value. This causes below warning message when
trying to remove the module.
