From a36c2638380c0a4676647a1f553b70b20d3ebce1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 22 Dec 2017 10:45:07 +0100 Subject: [PATCH] ALSA: hda: Drop useless WARN_ON() Since the commit 97cc2ed27e5a ("ALSA: hda - Fix yet another i915 pointer leftover in error path") cleared hdac_acomp pointer, the WARN_ON() non-NULL check in snd_hdac_i915_register_notifier() may give a false-positive warning, as the function gets called no matter whether the component is registered or not. For fixing it, let's get rid of the spurious WARN_ON().
