[PATCH v4 3/5] ALSA: ctxfi: ctatc: added reference to snd_card

From: Sudip Mukherjee
Date: Tue Sep 23 2014 - 07:01:16 EST


added reference of the card in the convert_format function
so that we can know which card has called the function.
this reference of the snd_card will actually be used in a later patch
to convert the pr_* macro to dev_*.
