0f6a5e50c4 ioexpander: add option to register GPIO by name for IOexpander 
Function gpio_lower_half_byname() was added to support registration of
GPIO pin by name as supported for IOexpander. Some of the code is wrapped
in new static function gpio_lower_half_internal() to avoid code
duplication.

6a3c2aded6 Fix wait loop and void cast (#24) 
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
