[ Upstream commit 7fb933e56f77a57ef7cfc59fc34cbbf1b1fa31ff ]
devm_clk_notifier_register() allocates a devres resource for clk notifier but didn't register that to the device, so the notifier didn't get unregistered on device detach and the allocated resource was leaked.
Fix the issue by registering the resource through devres_add().
This issue was found with kmemleak on a Chromebook.
