I was looking at the code here, but this code is under
drivers/media/video/davince/vpbe.c....

Are  you using the Linus tree?

BTW, this label is only used once. AFAICS, you can GOTO to the next
label, vpbe_fail_sd_register in this case, who frees another member of
the vpbe_dev.

This make sense to you?
