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.
