[alsa-devel] [PATCH] ASoC: core: Return -ENOTSUPP from set_sysclk() if no operation provided

From: Mark Brown broonie@linaro.org

Make it easier for generic code to work with set_sysclk() by distinguishing between the operation not being supported and an error as is done for other operations like set_dai_fmt()
