with the other defines, and I think it is good practice not to start with 0, just in

[media] tc358743: use - instead of non-ascii wide-dash character

smatch complains about non-ascii characters. It turns out that a wide-dash character
was used instead of the more common '-' character.

Replace those dashes with -.
