ACPI is performing a spin_lock() on a `void *'. That's OK when spin_lock is
implemented via an inline function. But when it is implemented via macros
(eg, with spinlock debugging enabled) we get:
drivers/acpi/osl.c:739: warning: dereferencing `void *' pointer
drivers/acpi/osl.c:739: request for member `owner' in something not a structure or union
So cast it to the right type.
