tty/vt: consolemap: introduce enum translation_map and use it
Again, instead of magic constants in the code, declare an enum and be a little bit more explicit. Both in the translations definition and in the loops etc. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Link: https://lore.kernel.org/r/20220607104946.18710-17-jslaby@suse.cz Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
