From e8fcffaf326f4d069aee4a6124e581ebe81f5a7e Mon Sep 17 00:00:00 2001 From: Otavio Salvador Date: Tue, 6 Jan 2015 13:43:35 -0200 Subject: kernel-module-mcc: Only include mvf_sema4.h if building in kernel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When mcc_config.h is used to make application we shouldn't include mvf_sema4.h as it is an internal symbol of kernel and shouldn't be directly referenced by user space applications using the MCC interface. This allows for application developers to use the SDK without having to copy the 'mvf_sema4.h' header byhand.
