2013-08-15ASoC: tegra20-ac97: simplify use of devm_ioremap_resourceJulia Lawall1-6/+0
Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@linaro.org>

This fixes the following by deleting dead code: sound/soc/tegra/tegra20_ac97.c: In function ‘tegra20_ac97_platform_probe’: sound/soc/tegra/tegra20_ac97.c:435:1: warning: label ‘err_unregister_pcm’ defined but not used [-Wunused-label] Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-29ASoC: tegra20-ac97: Remove unused variableThierry Reding1-1/+1
With the conversion to devm_ioremap_resource() the memregion variable is no longer used so it can be dropped. Signed-off-by: Thierry Reding <thierry.reding@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-29ASoC: tegra20-ac97: Remove duplicate error messageThierry Reding1-1/+0
devm_ioremap_resource() already outputs an error message when any of the operations it performs fails, so the duplicate in the caller can be removed. Signed-off-by: Thierry Reding <thierry.reding@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-27ASoC: ac97: Support multi-platform AC'97Mark Brown1-2/+10
Currently we can only have a single platform built in with AC'97 support due to the use of a global variable to provide the bus operations. Fix this by making that variable a pointer and having the bus drivers set the operations prior to registering. This is not a particularly good or nice approach but it avoids blocking multiplatform and a real fix involves fixing the fairly deep problems with AC'97 support - we should be converting it to a real bus.

Use the common DAI DMA data struct for tegra, this allows us to use the common helper function to configure the DMA slave config based on the DAI DMA data.
