Probe function is called only after DT compatible is matched, thus node pointer cannot be NULL.
Signed-off-by: Ladislav Michl ladis@linux-mips.org --- Note: this patch replaces previously sent "ASoC: sam9x5_wm8731: Return -ENODEV when probe does not find OF node" and "ASoC: atmel_wm8904: Return -ENODEV when probe does not find OF node" while taking Alexandre Belloni's advice into account and extending it for the rest of Atmel's drivers.
