[PATCH] clk: tegra30: make tegra_clk_pll_params __ro_after_init

From: Bhumika Goyal
Date: Mon Oct 02 2017 - 16:14:23 EST


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.
