Subject: [PATCH net-next v2 1/2] ACPI: utils: Add acpi_evaluate_dsm_typed() and acpi_check_dsm() stubs
Date: Thu, 19 Jan 2023 21:11:00 +0200 [thread overview]
Message-ID: <20230119191101.80131-1-andriy.shevchenko@linux.intel.com> (raw)
When the ACPI part of a driver is optional the methods used in it
are expected to be available even if CONFIG_ACPI=n. This is not
the case for _DSM related methods. Add stubs for
acpi_evaluate_dsm_typed() and acpi_check_dsm() methods.
