RE: [PATCH -mm] acpi: handle firmware_register init errors

This is syntatically correct, and I'll apply it.

For this to actually trigger, it appears that create_dir()
would have to fail, which is hard to imagine.

One might question the value of /sys/firmware/acpi based
on the fact that the only thing we do differently if we
can't create it is print a message...
