Subject: ASoC: tas2552: Fix kernel crash when the codec is loaded but not part
of a card
From: Peter Ujfalusi <[email protected]>
commit 80ba2669ec8c3e6517aa935001f6cb8809bf3df4 upstream.
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.
