The memory allocations in au0828_init_isoc() happen all in task context with GFP_KERNEL. Therefore a printk() trying to deduce whether this is called from task or interrupt context is pretty useless. Convert it to au0828_isocdbg() as the other one in that function and for completeness sake add one for the URB allocation as well.
