Hi,
BTW, memory allocation in 'sun4i_layers_init()' looks spurious, especially the use of 'layer' in the for loop. Just my 2 cents.
I also forgot to say that we could propagate the error code returned by sun4i_layers_init instead of returning -EINVAL unconditionally

'sun4i_layers_init()' returns an error pointer in case of error, not NULL. So test it with IS_ERR.
