From: Colin Ian King <colin.king@canonical.com>
Don't populate the gain tables on the stack but make them static const. Makes the object code smaller:
Before: text data bss dec hex filename 7801 1408 0 9209 23f9 drivers/media/tuners/fc0012.o 8483 936 0 9419 24cb drivers/media/tuners/fc0013.o
After: text data bss dec hex filename 7696 1464 0 9160 23c8 drivers/media/tuners/fc0012.o 8362 1024 0 9386 24aa drivers/media/tuners/fc0013.o
