security: declare member holding string literal const
The struct security_hook_list member lsm is assigned in security_add_hooks() with string literals passed from the individual security modules. Declare the function parameter and the struct member const to signal their immutability. Reported by Clang [-Wwrite-strings]: security/selinux/hooks.c:7388:63: error: passing 'const char [8]' to parameter of type 'char *' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers] security_add_hooks(selinux_hooks, ARRAY_SIZE(selinux_hooks), selinux); ^~~~~~~~~ ./include/linux/lsm_hooks.h:1629:11: note: passing argument to parameter 'lsm' here char *lsm); ^ Signed-off-by: Christian Göttsche <cgzones@googlemail.com> Reviewed-by: Paul Moore <paul@paul-moore.com> Reviewed-by: Casey Schaufler <casey@schaufler-ca.com> Signed-off-by: Paul Moore <paul@paul-moore.com>
