From ae364fd917a23c926367a84a0d5aca7f0e6ab3dd Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 13 Oct 2021 18:08:06 +0200 Subject: nouveau: ACPI: Use the ACPI_COMPANION() macro directly The ACPI_HANDLE() macro is a wrapper arond the ACPI_COMPANION() macro and the ACPI handle produced by the former comes from the ACPI device object produced by the latter, so it is way more straightforward to evaluate the latter directly instead of passing the handle produced by the former to acpi_bus_get_device(). Modify nouveau_acpi_edid() accordingly (no intentional functional impact). Signed-off-by: Rafael J.
