For development, sure, if there's sufficient memory.

For embedded systems with limited memory, using
dynamic_debug isn't always possible or effective.

Also, there are sometimes reasons to have debugging
messages always enabled or emitted.

For those cases, either adding #define DEBUG or using
printk(KERN_DEBUG would be fine.
