Subject: [PATCH 02/10] arm: Add prototypes for functions called from assembly
Date: Tue, 15 Sep 2020 14:25:31 +0200	[thread overview]
Message-ID: <20200915122539.18744-3-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200915122539.18744-1-s.hauer@pengutronix.de>

Some functions are called from assembly only. There's no prototype
for them so this leads to -Wmissing-prototypes warnings. Add a prototype
right aboce the functions to avoid these warnings.
