Subject: [PATCH] clk: pxa: Constify static struct clk_ops
Date: Tue, 22 Sep 2020 20:47:15 +0200 [thread overview]
Message-ID: <20200922184715.1854-1-rikard.falkeborn@gmail.com> (raw)
Constify a couple of static struct clk_ops that are not modified. Their
only usage is inside the macros and their address is passed to
clk_register_composite() which takes pointers to const struct clk_ops.
This allows the compiler to put them in read-only memory.
