Subject: [PATCH 4/5] clk: ingenic: Remove unused functions
Date: Tue,  7 May 2019 21:34:20 +0200	[thread overview]
Message-ID: <20190507193421.12260-4-paul@crapouillou.net> (raw)
In-Reply-To: <20190507193421.12260-1-paul@crapouillou.net>

These functions are not called anywhere anymore, they can safely be
removed.
