Right, I'm pretty sure the soc framework depends on dev_get_drvdata
returning the snd_soc_card and I forgot about this when adding
the remove function.

Wei Yongjun, thank you for catching this.

Dan, thank you for the correct version of the patch :)

Dan, can you do an official submission of the correct version of the
patch, with a Reported-by: Wei Yongjun <weiyongjun1@huawei.com>
or shall I submit your version upstream ?

Regards,

Hans
