Subject: [PATCH] of: clk: Make of_clk_get_parent_{count,name}() parameter const
Date: Wed, 12 Feb 2020 10:43:17 +0100 [thread overview]
Message-ID: <20200212094317.1150-1-geert+renesas@glider.be> (raw)
of_clk_get_parent_count() and of_clk_get_parent_name() never modify the
device nodes passed, so they can be const.
