This patch set did some Optimization with changing to use devm_xxx()
APIs to simplify the code and make code more readable.
Baolin Wang (3):
hwspinlock: u8500_hsem: Change to use
devm_platform_ioremap_resource()
hwspinlock: u8500_hsem: Use devm_kzalloc() to allocate memory
hwspinlock: u8500_hsem: Use devm_hwspin_lock_register() to register
hwlock controller
