Subject[PATCH] mmc: dw_mmc: hi3798cv200: make array degrees static const, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the array degrees on the stack but instead make it
static const. Makes the object code smaller by 46 bytes.

Before:
text data bss dec hex filename
5356 1560 0 6916 1b04 dw_mmc-hi3798cv200.o

After:
text data bss dec hex filename
5214 1656 0 6870 1ad6 dw_mmc-hi3798cv200.o

(gcc version 9.2.1, amd64)
