[PATCH 0/4] crypto: constify struct debugfs_reg32

[Rikard Falkeborn]

A small series constifying struct debugfs_reg32 where it can be made
const. There's no dependency between the patches.

Rikard Falkeborn (4):
  crypto: ccree - constify struct debugfs_reg32
  crypto: hisilicon/hpre - constify struct debugfs_reg32
  crypto: hisilicon/zip - constify struct debugfs_reg32
  crypto: hisilicon/sec2 - constify sec_dfx_regs

[PATCH 1/4] crypto: ccree - constify struct debugfs_reg32

[Rikard Falkeborn]

pid_cd_regs and debug_regs are 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
   2871    2320      64    5255    1487 drivers/crypto/ccree/cc_debugfs.o
