Subject: [PATCH] clk: tegra30: make tegra_clk_pll_params __ro_after_init
Date: Tue, 3 Oct 2017 01:42:08 +0530 [thread overview]
Message-ID: <1506975128-16514-1-git-send-email-bhumirks@gmail.com> (raw)
These structures are only passed to the functions tegra_clk_register_pll,
tegra_clk_register_pll{e/u} or tegra_periph_clk_init during the init
phase. These functions modify the structures only during the init phase
and after that the structures are never modified. Therefore, make them
__ro_after_init.
