From cc0282975b3f887005c380adcf0af95915f0c1bb Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 6 Dec 2018 20:07:40 +0000 Subject: kgdb/treewide: constify struct kgdb_arch arch_kgdb_ops checkpatch.pl reports the following: WARNING: struct kgdb_arch should normally be const #28: FILE: arch/mips/kernel/kgdb.c:397: +struct kgdb_arch arch_kgdb_ops = { This report makes sense, as all other ops struct, this one should also be const. This patch does the change.
