Subject: [PATCH v3 2/5] acpi/ssdt: Fix aml_or() and aml_and() in if clause
Date: Thu,  1 Sep 2022 11:27:18 +0800	[thread overview]
Message-ID: <20220901032721.1392482-3-robert.hu@linux.intel.com> (raw)
In-Reply-To: <20220901032721.1392482-1-robert.hu@linux.intel.com>

In If condition, using bitwise and/or, rather than logical and/or.

The result change in AML code:

If (((Local6 == Zero) | (Arg0 != Local0)))
==>
If (((Local6 == Zero) || (Arg0 != Local0)))

If (((ObjectType (Arg3) == 0x04) & (SizeOf (Arg3) == One)))
==>
If (((ObjectType (Arg3) == 0x04) && (SizeOf (Arg3) == One)))

Fixes: 90623ebf603 ("nvdimm acpi: check UUID")
Fixes: 4568c948066 ("nvdimm acpi: save arg3 of _DSM method")
