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
