Commit Message

Christophe JAILLET May 10, 2024, 4:50 p.m. UTC 
pll_vco structure are never modified. They are used as .vco_table in
"struct clk_alpha_pll".

And in this structure, we have:
	const struct pll_vco *vco_table;

Constifying these structures moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig:
Before:
   text	   data	    bss	    dec	    hex	filename
   9905	  47576	      0	  57481	   e089	drivers/clk/qcom/mmcc-msm8994.o

After:
   text	   data	    bss	    dec	    hex	filename
  10033	  47440	      0	  57473	   e081	drivers/clk/qcom/mmcc-msm8994.o

Compile tested only.

I hope that it can be applied with this single patch because all files are
in drivers/clk/qcom/.
