Subject: [PATCH] ASoC: core: Fix possible NULL pointer dereference

snd_soc_of_parse_card_name() may be called before card->dev has been
set, which results in a kernel panic.

Unable to handle kernel NULL pointer dereference at virtual address 00000210
PC is at snd_soc_of_parse_card_name+0x18/0x54
LR is at snow_probe+0x5c/0xd4

Add an error check in snd_soc_of_parse_card_name() to take care of this
case and print out a message in case of error.
