Subject[PATCH] mmc: dw_mmc: make const arrays mszs static
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the const arrays mszs on the stack, instead make them
static. Makes the object code smaller by over 310 bytes:

Before:
text data bss dec hex filename
47527 8528 320 56375 dc37 drivers/mmc/host/dw_mmc.o

After:
text data bss dec hex filename
47055 8688 320 56063 daff drivers/mmc/host/dw_mmc.o
