ath5k: constify stuff
Make some structures const to place them in .rodata, since we won't change them. Most important parts of objdump -h: - 0 .text 00011170 + 0 .text 00011140 - 5 .rodata 0000828e + 5 .rodata 0000895e - 13 .data 00000560 + 13 .data 00000110 - 14 .devinit.data 00000260 Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Cc: Luis R.
