block/DAC960.c: make some arrays static const, shrinks object size
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) Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
