From 0e9b9edae7bebfd31fdbead4ccbbce03876a7edd Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Thu, 19 May 2016 15:19:25 +0200 Subject: [PATCH] acpi: convert linker from GArray to BIOSLinker structure Patch just changes type of of linker variables to a structure, there aren't any functional changes. Converting linker to a structure will allow to extend it functionality in follow up patch adding sanity blob checks. Signed-off-by: Igor Mammedov Reviewed-by: Michael S.
