why static const char instead of #define? This is only used one time in a
pr_info, so it seems kind of pointless anyway.


Other drivers are using static const for the same variable.
i think static const is preferred over #define because #define doet give a
type.
If you dont mind ill keep it static const.


If this string was used in this file more than one place, I would agree with
you, but currently it is only used as the argument of a pr_info(). The
string "ohci-da8xx" could just be included in the fmt string instead of
using "%s".

I think the purpose was to use it in the .name of the platform_driver
structure, too. only that not everybody is doing that, i looked at some bad
examples :(

would you agree to keep it if we use it in .name too?

Yes, that will make more sense. ;-)
