If it's only used by one source file, it doesn't need to be in a header file, which is implicitly for sharing information between multiple source files. The worst is when you have foo_driverreg.h with like 4 #defines in it; that's so annoying. (A valid exception to the "only if it needs to be shared" concept might be a file that #defines hundreds-to-thousands of values.) -- Ian > There are some style issues with your patch, but I think it's pretty close to being ready. > > -- > Rui Paulo > > > > _______________________________________________ > freebsd-arm@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-arm > To unsubscribe, send any mail to "freebsd-arm-unsubscribe@freebsd.org"
