ec/google/chromeec: Fix ACPI FWTS error
Fix the following FWTS error:
FAILED [MEDIUM] AMLAsmASL_MSG_RETURN_TYPES: Test 1, Assembler warning in line
3038
Line | AML source
--------------------------------------------------------------------------------
03035| Return (One)
03036| }
03037|
03038| Method (_Q09, 0, NotSerialized) // _Qxx: EC Query
| ^
| Warning 3115: Not all control paths return a value (_Q09)
03039| {
03040| If (Acquire (PATM, 0x03E8))
03041| {
================================================================================
ADVICE: (for Warning #3115, ASL_MSG_RETURN_TYPES): Some of the execution paths
do not return a value. All control paths that return must return a value
otherwise unexpected behaviour may occur. This error occurs because a branch on
an conditional op-code returns a value and another does not, which is
inconsistent behaviour.
_Q09 is a reserved method and can't return a value. Change the logic
so that no return is used and avoid this test error.
BUG=b:112476331
TEST=Run FWTS.
