V4L/DVB: drivers/media: Make static data tables and strings const
Making static data const avoids allocation of additional r/w memory and reduces initialisation time. It also provides some additional opportunities for compiler optimisations. Signed-off-by: Lawrence Rust <lvr@softsystem.co.uk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
