Subject: [PATCH 5/6] powerpc: Remove unused functions
Date: Tue, 15 Sep 2020 09:03:04 +0200	[thread overview]
Message-ID: <20200915070305.15763-6-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200915070305.15763-1-s.hauer@pengutronix.de>

Some functions are unused in the code base and do not have a prototype
in any header file. Remove them.
