Vendor drivers no longer access a DAI link's runtime by the link index but by matching the link name via snd_soc_get_pcm_runtime(). We assume each DAI link has a unique name. This is preparation for changing runtimes from an array to a list later. Vendor drivers changed: sound/soc/fsl/fsl-asoc-card.c sound/soc/fsl/imx-wm8962.c sound/soc/pxa/mioa701_wm9713.c sound/soc/samsung/bells.c sound/soc/samsung/littlemill.c sound/soc/samsung/odroidx2_max98090.c sound/soc/samsung/snow.c sound/soc/samsung/speyside.c sound/soc/samsung/tobermory.c sound/soc/tegra/tegra_wm8903 Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
