ALSA: aoa: Remove direct OF name and type accesses
Convert soundbus uevent and sysfs OF node name and device type usage to use printf specifier and helper functions instead of directly accessing the name and type pointers. This will allow the eventual removal of the pointers. Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
