"Device", "OperationRegion", are not recognized.
Note: The same ACPI control method can be overridden for many times,
and it's always the latest one that used by Linux/kernel.
+Note: To get the ACPI debug object output (Store (AAAA, Debug)),
+ please run "echo 1 > /sys/module/acpi/parameters/aml_debug_output".
1. override an existing method
a) get the ACPI table via ACPI sysfs I/F. e.g. to get the DSDT,
This does all the RCU magic inside of it. The caller must call put_cred() on
the credentials so obtained when they're finished with.
+ [*] Note: The result of __task_cred() should not be passed directly to
+ get_cred() as this may race with commit_cred().
+
There are a couple of convenience functions to access bits of another task's
credentials, hiding the RCU magic from the caller:
