PCI: acpiphp: Allow built-in drivers for Attention Indicators
Since the introduction of the attention callback in acpiphp, a non-zero
struct module *owner has been required in acpiphp_register_attention(). The
intent seemed to be that the core code could hold a refcount on the module
while invoking a callback.
This check accidentally precludes the possibility of attention callbacks to
built-in drivers.
Remove the check on `struct module *owner` in acpiphp_register_attention()
so attention callbacks can also be registered from built-in drivers.
