MIPS is the only architecture modifying arch_kgdb_ops during init. This patch makes the init static, so that it can be changed to const in following patch, as recommended by checkpatch.pl Suggested-by: Paul Burton <paul.burton@mips.com> Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> --- arch/mips/kernel/kgdb.c | 16 +++++++--------- 1 file changed, 7 insertions(+), 9 deletions(-)
