vt: switch G0/1_charset to an array
Declare Gx_charset[2] instead of G0_charset and G1_charset. It makes the code simpler (without ternary operators). Signed-off-by: Jiri Slaby <jslaby@suse.cz> Link: https://lore.kernel.org/r/20200615074910.19267-5-jslaby@suse.cz Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
