Enabling both the old AC97_BUS code and the new AC97_BUS_COMPAT causes problems because both modules provide an exported snd_ac97_reset() function.
I had tried to fix the problem of having both coexist earlier, but my patch only prevented them from being built-in. This is because of a special Kconfig feature that lets a symbol have a dependency on another one being disabled, but still allow both to be loadable modules.
Changing the dependency to =n avoids that problem, now we can only build the new driver if the old one is completely disabled.
If we could figure out a way to let rename one of the reset functions and have each driver link to exactly the old or the compat code, that would also work, but I could not find if that's possible.
