[PATCH 3/3] hwspinlock: omap: Use devm_hwspin_lock_register() to register hwlock controller

From: Baolin Wang
Date: Wed Dec 04 2019 - 04:32:20 EST


Use devm_hwspin_lock_register() to register the hwlock controller instead of
unregistering the hwlock controller explicitly when removing the device.
