From: Colin Ian King <redacted> Don't populate const arrays on the stack, instead make them static. Makes the object code smaller by over 60 bytes: Before: text data bss dec hex filename 14816 1296 0 16112 3ef0 b43/phy_ht.o After: text data bss dec hex filename 14551 1496 0 16047 3eaf b43/phy_ht.o (gcc 6.3.0, x86-64) Signed-off-by: Colin Ian King <redacted> --- drivers/net/wireless/broadcom/b43/phy_ht.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-)
