Subject: [PATCH 1/2] mips/kgdb: prepare arch_kgdb_ops for constness
Date: Wed, 5 Dec 2018 04:41:09 +0000 (UTC) [thread overview]
Message-ID: <75bbcdd1e9277d66ebb06e349dda304bd01ce761.1543957194.git.christophe.leroy@c-s.fr> (raw)
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>
