Subject: [PATCH] ALSA: hda: Fix forget to free resource in error handling code path in hda_codec_driver_probe
Date: Sun, 3 Sep 2017 22:11:22 +0800	[thread overview]
Message-ID: <20170903141122.GA2848@udknight> (raw)

When hda_codec_driver_probe meet error and return failure, we need
to free resource with patch_ops.free, or we will get resource leak.
