From acc98c1f2a1b4503588d3b1eb35db9cb76abdd89 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Fri, 27 Sep 2019 16:27:43 +0800 Subject: [PATCH] hwspinlock: u8500_hsem: Use devm_hwspin_lock_register() to register hwlock controller Use devm_hwspin_lock_register() to register the hwlock controller instead of unregistering the hwlock controller explicitly when removing the device.
