Subject: [PATCH v2 5/6] powerpc: Remove 'extern' from func prototypes in cache headers
Date: Tue, 3 Sep 2019 15:23:59 +1000 [thread overview]
Message-ID: <20190903052407.16638-6-alastair@au1.ibm.com> (raw)
In-Reply-To: <20190903052407.16638-1-alastair@au1.ibm.com>
From: Alastair D'Silva <alastair@d-silva.org>
The 'extern' keyword does not value-add for function prototypes.
