[PATCH] clk: Fix memory leak in devm_clk_notifier_register()

[Fei Shao]

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.

This fixes the issue.
