Subject: [PATCH 3/9] ACPICA: Macros: remove pointer math on a null pointer
Date: Fri, 16 Aug 2019 14:43:22 -0700	[thread overview]
Message-ID: <20190816214328.3900-4-erik.schmauss@intel.com> (raw)
In-Reply-To: <20190816214328.3900-1-erik.schmauss@intel.com>

From: Bob Moore <robert.moore@intel.com>

ACPICA commit 02bbca5070e42d298c9b824300aa0eb8a082d797

Causes warnings on some compilers and/or tools.
Changed ACPI_TO_POINTER to use ACPI_CAST_PTR instead of using
arithmetic.
