[Patch v2 1/2] ASoC: atmel: sam9x5_wm8731: fix oops when unload module

[Bo Shen <voice.shen@xxxxxxxxx>]

As the priv is not assigned to card->drvdata, it is NULL, so when
unload module, it will cause NULL pointer oops.
Assign priv to card->drvdata to fix this issue.

Signed-off-by: Bo Shen <voice.shen@xxxxxxxxx>

Change in v2: 
  - using snd_soc_card_set_drvdata()
