[alsa-devel] [PATCH v2] ASoC: remove a card from the list, if instantiation failed

[Guennadi Liakhovetski]

If instantiation of a card failed, we still have to remove it from the 
card list on unregistration. This fixes an Oops on Migo-R, triggering, 
when after a failed firmware load attempt the driver modules are removed 
and re-inserted again.

Mark, is this more like what you mean?
