From 26de5d0a8df0817a58422f6ad43019c47716ce1f Mon Sep 17 00:00:00 2001 From: Eldad Zack Date: Sun, 6 Oct 2013 22:31:07 +0200 Subject: [PATCH] ALSA: usb-audio: remove deactivate_endpoints() The only call site for deactivate_endpoints() at snd_usb_hw_free(). The return value is not checked there, as it is irrelevant if it fails on hw_free. This patch moves the deactivation of the endpoints directly into snd_usb_hw_free().
