Subject: [PATCH 3/4] crypto: hisilicon/zip - constify struct debugfs_reg32
Date: Sat,  9 May 2020 00:35:01 +0200	[thread overview]
Message-ID: <20200508223502.7258-4-rikard.falkeborn@gmail.com> (raw)
In-Reply-To: <20200508223502.7258-1-rikard.falkeborn@gmail.com>

hzip_dfx_regs is never changed and can 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
  15236    6160     480   21876    5574 drivers/crypto/hisilicon/zip/zip_main.o

After:
   text    data     bss     dec     hex filename
  15620    5776     480   21876    5574 drivers/crypto/hisilicon/zip/zip_main.o
