[PATCH] clk: bcm2835: Constify struct debugfs_reg32

From: Rikard Falkeborn
Date: Fri May 08 2020 - 18:02:45 EST


bcm2835_debugfs_clock_reg32 is never changed and can therefore be made
const.

This allows the compiler to put it in the text section instead of the
data section.

Before:
text data bss dec hex filename
26598 16088 64 42750 a6fe drivers/clk/bcm/clk-bcm2835.o

After:
text data bss dec hex filename
26662 16024 64 42750 a6fe drivers/clk/bcm/clk-bcm2835.o
