From 6f0217441839c258b82dd83ee15082666d6ab9c2 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Thu, 17 Mar 2016 21:14:36 +0900 Subject: [PATCH] ALSA: ctl: change return value in compatibility layer so that it's the same value in core implementation In control compatibility layer, when no elements are found by ELEM_READ/ELEM_WRITE ioctl commands, ENXIO is returned. On the other hand, in core implementation, ENOENT is returned. This is not good for ALSA ctl applications. This commit changes the return value from the compatibility layer so that the same value is returned.
