From 192a7122954001af2504a9abecfc0ad28532a6ee Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 5 Dec 2018 13:50:48 -0600 Subject: 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.
