From 86fca926c042138c7defc94e1b55b5f29ca4fa13 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 26 Jun 2023 14:00:23 +0300 Subject: ACPI: bus: Constify acpi_companion_match() returned value acpi_companion_match() doesn't alter the contents of the passed parameter, so we don't expect that returned value can be altered either. So constify it. Signed-off-by: Andy Shevchenko Signed-off-by: Rafael J.
