From: Colin Ian King <colin.king@canonical.com>
Don't populate the const array bws on the stack but instead it static. Makes the object code smaller by 80 bytes:
Before: text data bss dec hex filename 85694 16865 1216 103775 1955f ./net/wireless/reg.o
After: text data bss dec hex filename 85518 16961 1216 103695 1950f ./net/wireless/reg.o
(gcc version 10.2.0)
