Subject: [PATCH v2 02/23] ASoC: tas2552: Fix kernel crash when the codec is loaded but not part of a card
Date: Thu, 4 Jun 2015 16:04:14 +0300 [thread overview]
Message-ID: <1433423075-14142-3-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1433423075-14142-1-git-send-email-peter.ujfalusi@ti.com>
If the card is not part of any card the tas_data->codec is NULL since it is
set only during snd_soc_codec_driver.probe, which is not yet called.
