- process pending queries in EcUnlock() to close a race window.
now there's no need to do polling for EcQuery().
- reorder inline functions and other prototypes so that
the formers can get needed prototypes.
- add missing prototypes.
it can now accomodate multiple _CIDs
sizeof(ACPI_DEVICE_INFO) should not be used
* make ad_devinfo member in acpi_devnode a pointer
* implement acpi_match_hid() to simplify matching devices;
_CIDs are also taken into account now as well as _HID
acpi_is_global_locked() functions.
AcpiGlobalLock() API should be used to acquire lock between BIOS and OS.
This API cannot be used to lock between threads of the OS side,
because this function immediately returns if the lock is already acquired
by the OS. c.f. AcpiEvAcquireGlobalLock()@evmisc.c
- make sure that acpiec driver uses above functions.
- use ACPI_ALLOCATE_BUFFER instead of twice calls of AcpiEvaluateObject(),
in acpi_eval_string()/acpi_eval_struct().
Twice AcpiEvaluateObject() calls may cause twice side effects
to ACPI machine / hardware and this may be wrong in some cases.
