dyndbg: use ESCAPE_SPACE for cat control
`cat control` currently does octal escape, so '\n' becomes "\012". Change this to display as "\n" instead, which reads much cleaner. :#> head -n7 /proc/dynamic_debug/control # filename:lineno [module]function flags format init/main.c:1179 [main]initcall_blacklist =_ "blacklisting initcall %s\n" init/main.c:1218 [main]initcall_blacklisted =_ "initcall %s blacklisted\n" init/main.c:1424 [main]run_init_process =_ " with arguments:\n" init/main.c:1426 [main]run_init_process =_ " %s\n" init/main.c:1427 [main]run_init_process =_ " with environment:\n" init/main.c:1429 [main]run_init_process =_ " %s\n" Acked-by: Jason Baron <jbaron@akamai.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Link: https://lore.kernel.org/r/20220904214134.408619-7-jim.cromie@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
