Dan Carpenter 8c58f51ff3 pinctrl: realtek: Fix error handling in probe() 
There are several issues in the probe function:
1) of_iomap() return NULL on error but the code checks for error
   pointers.
2) pinctrl_register() is the reverse.  It returns error pointers
   but the code checks for NULL.
3) The error paths need to call iounmap(data->base) before returning
   to avoid a resource leak.
