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

[Mark Brown]

From: Mark Brown <broonie at 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()
