From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Don't populate the arrays ReadCacheStatus, WriteCacheStatus and
SenseErrors on the stack but instead make them static const. Makes
the object code smaller by 47 bytes:
Before:
text data bss dec hex filename
160974 34628 832 196434 2ff52 drivers/block/DAC960.o
After:
text data bss dec hex filename
160671 34884 832 196387 2ff23 drivers/block/DAC960.o
(gcc version 8.2.0 x86_64)
