Keith, it is getting weird right now. Your above suggestion does not work, it
does not even execute, because the braces obviously confuse it.
Now I come up with a _working_ solution, but to be honest, I don't dare to give
away the patch, because it looks like this:
EXTRA_CFLAGS += -DHISAX_MAX_CARDS=$(subst ,,$(CONFIG_HISAX_MAX_CARDS))
You read it right, no substition is going on. BUT my test shows this executes
to e.g. "8" and not "(8)". This is what I wanted, but it looks like bs.
Alan would you please tell me if this looks like clean make usage to you, or
how you would drop "()" around integer definitions coming from CONFIG. Warning:
if you think this is ok, I will send the patch ;-) I only want a confirmation
from "Mr. Clean Code" ;-))
Regards,
Stephan
