From 23818b3d8590a79d56af9659cf709ebfae30f832 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Fri, 3 Apr 2020 18:10:18 +0100 Subject: firmware: arm_scpi: Add include guard to linux/scpi_protocol.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If this header is include twice, it will generate loads of compile time error with the following below error pattern. It was reported by 0day kbuild robot on a branch pushed with double inclusion by accident. This is based on the similar change in linux/scmi_protocol.h error: conflicting types for ‘...’ note: previous declaration of ‘...’ was here error: redefinition of ‘...’ Add a header include guard just in case.
