From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mark Brown Date: Mon, 11 Jul 2011 02:53:53 +0000 Subject: [PATCH 2/6] clk: Provide a dummy clk_unregister() Message-Id: <1310352837-4277-2-git-send-email-broonie@opensource.wolfsonmicro.com> List-Id: References: <20110711025344.GA27497@opensource.wolfsonmicro.com> <1310352837-4277-1-git-send-email-broonie@opensource.wolfsonmicro.com> In-Reply-To: <1310352837-4277-1-git-send-email-broonie@opensource.wolfsonmicro.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org Even though unregistration is not actually supported by the clk API it is still useful to provide a clk_unregister() so that drivers can implement their unregistration code. This saves having to go back later and update them once unregistration is possible.
