So IMHO I think going for all in one source would be thebest. Should I move the AC97C driver to sound/drivers instead then, and thenleave it open for you to implement the extra parts for AT91 devices? -- Best regards,Hans-Christian Egtvedt_______________________________________________Alsa-devel mailing listAlsa-devel@xxxxxxxxxxxxxxxxxxxx://mailman.alsa-project.org/mailman/listinfo/alsa-devel
