From 9badda0a0afffebbe1cb30565800896534a6c5bd Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Jan 2012 18:22:35 +0100 Subject: [PATCH] ALSA: hdsp - Fix potential Oops in snd_hdsp_info_pref_sync_ref() Dan Carpenter reported that setting 0 to uinfo->value.enumerated.items in snd_hdsp_info_pref_sync_ref() may lead to Oops. This function should return an error immediately in such a case instead.
