Subject: [PATCH v1 1/1] ACPI: NFIT: Switch to use acpi_evaluate_dsm_typed()
Date: Mon, 2 Oct 2023 16:54:58 +0300 [thread overview]
Message-ID: <20231002135458.2603293-1-andriy.shevchenko@linux.intel.com> (raw)
The acpi_evaluate_dsm_typed() provides a way to check the type of the
object evaluated by _DSM call. Use it instead of open coded variant.
