Subject: [PATCH] clk: spear: Make structure i2s_sclk_masks constant
Date: Tue, 13 Aug 2019 14:27:14 +0530
Message-ID: <20190813085714.8079-1-nishkadg.linux@gmail.com> (raw)

Static structure i2s_sclk_masks, having type aux_clk_masks, is only used
when it is passed as the sixth argument to function clk_register_aux().
However, clk_register_aux() is defined with its sixth argument as const.
Hence i2s_sclk_masks is not modified by clk_register_aux, which is also
the only usage of the former. Therefore make i2s_sclk_masks constant as
it is never modified.
Issue found with Coccinelle.
