#1284028 — [PATCH 3/3] clk: tegra-super: Fix sparse warnings for functions not declared as static

Sparse reports the following warnings for structures and functions that
should be declared static:

drivers/clk/tegra/clk-tegra-super-gen4.c:70:35: warning: symbol
 'tegra_super_gen_info_gen4' was not declared. Should it be static?
drivers/clk/tegra/clk-tegra-super-gen4.c:96:35: warning: symbol
 'tegra_super_gen_info_gen5' was not declared. Should it be static?
drivers/clk/tegra/clk-tegra-super-gen4.c:174:13: warning: symbol
 'tegra_super_clk_init' was not declared. Should it be static?

Fix this by making the above static.

Fixes: 88467d220119 ("clk: tegra: Add Super Gen5 Logic")

Actually, Don't you need to change the function declarations in
drivers/clk/tegra/clk.h for tegra_super_clk_gen[4|5]_init otherwise you
will get mismatches with one being declared static and the other not?

So this patch does not touch the functions
tegra_super_clk_gen[4|5]_init() and these should definitely not be
static. This patch just makes the structures
tegra_super_gen_info_gen[4|5] and the function tegra_super_clk_init()
static. None of these are referenced outside clk-tegra-super-gen4.c.

Cheers
Jon
