* ASoC: qcom: remove duplicate initializations of dma_ch and vColin Ian King2017-09-191-2/+0Star
| | | | | | | | | | | | | | | | dma_ch is being initialized to zero and then immediately afterwards being updated again, so the first initialization is redundant and can be remove. Likewise, the pointer v is being initialized twice, so remove the second duplicate initialization. Cleans up two clang build warnings: warning: Value stored to 'dma_ch' is never read warning: Value stored to 'v' during its initialization is never read Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Remove the usage of __func__ to clean the kernel log and as the usage is not necessary to identify the individual log prints.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 022d00ee0b55 ("ASoC: lpass-platform: Fix broken pcm data usage") the stream specific information initialization was broken, with the dma channel information not being initialized if there was no alloc_dma_channel() helper function. Before that, the DMA channel number was implicitly initialized to zero because the backing store was allocated with devm_kzalloc(). When the init code was rewritten, that implicit initialization was lost, and gcc rightfully complains about an uninitialized variable being used.

* | ASoC: lpass-platform: Fix broken pcm data usageSrinivas Kandagatla2016-10-311-86/+79Star
|/ | | | | | | | | | | | | | | | | | This patch fixes lpass-platform driver which was broken in v4.9-rc1. lpass_pcm_data data structure holds information specific to stream. Holding a single private pointer to it in global lpass_data will not work, because it would be overwritten by for each pcm instance. This code was breaking playback when we have both playback and capture pcm streams, as playback settings are over written by capture settings. Fix this by moving channel allocation logic out of pcm_new to pcm_open so that we can store the stream specific information in private_data of snd_pcm_runtime.

* ASoC: qcom: use correct device pointer in dma allocationSrinivas Kandagatla2016-01-111-9/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | dev pointer in struct snd_soc_pcm_runtime does not have dma_ops set. In v4.4 kernel dma_ops would end up pointing to dummy_dma_ops in such cases. So attempting to use such device in allocating coherent memory on aarch64 would fail. According to commit 1dccb598df549d892b6450c261da54cdd7af44b4 ("arm64: simplify dma_get_ops") The current behavior of dma_get_ops is to fall back to the global dma_ops when a device has not set its own dma_ops, but only for DT based systems. So, this patch fixes the driver to use correct device pointer while allocating coherent memory, and also deletes un-necessary dma_mask setup on soc_runtime->dev. Without this patch lpass driver would fail with below log: ...
