From 35b7ebda57affcfd3616d39d5a727a4495b31123 Mon Sep 17 00:00:00 2001 From: Michael Zoran Date: Wed, 19 Oct 2016 15:58:09 -0700 Subject: [PATCH] staging: vc04_services: Convert dsb() to dsb(sy) The dsb() macro for 32 arm compiles to dsb(sy) in the binary file. This macro is no longer supported on arm64, so instead use dsb(sy) which is completely binary compatible.
