From 719cf71cada1abc4f8727eac918b639a4a502a59 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 20 Aug 2018 16:45:41 +0300 Subject: [PATCH] ACPI / glue: Split dev_is_platform() out of module for wide use There would be useful to have in future the similar API in platform core, as we have, for example, for PCI subsystem, to check if device belongs to it. Thus, split out conditional to a macro dev_is_platform() for wide use. No functional change intended. Signed-off-by: Andy Shevchenko Signed-off-by: Rafael J.
