Bug 11884 - _REG and _INI

[Lin Ming <ming.m.lin@intel.com>]

http://bugzilla.kernel.org/show_bug.cgi?id=11884 

Method(\_SB._INI)
{
	//initialize package CUZO
}

Method(\_SB_.PCI0.LPCB.EC0_._REG)
{
	//access package CUZO
}

For this machine, \_SB._INI must be run before \_SB_.PCI0.LPCB.EC0_._REG

But currently early EC _REG method is run before _INI as below acpi_bus_init shows.

void __init acpi_bus_init(void)
         .....
         status = acpi_ec_ecdt_probe();
         /* Ignore result. Not having an ECDT is not fatal. */

         status = acpi_initialize_objects(ACPI_FULL_INITIALIZATION);
         .....
}

acpi_ec_ecdt_probe will install ec handler although no ECDT found in this machine.

Alexey, 
How about that if there's no ECDT found, we do not install ec handler before acpi_initialize_objects?
