ASoC: rockchip: Fix an error handling in 'rockchip_i2s_probe'
If this memory allocation fail, we must disable what has been enabled. Do not return immediately but go thrue the error handling path instead. Also use 'devm_kmemdup' instead of 'devm_kzalloc+memcpy' to simplify code. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
