ASoC: Intel: Fix use of potentially uninitialized variable

2019-10-05T11:14:06+00:00

commit 810f3b860850148788fc1ed8a6f5f807199fed65 upstream. If ipc->ops.reply_msg_match is NULL, we may end up using uninitialized mask value. reported by smatch: sound/soc/intel/common/sst-ipc.c:266 sst_ipc_reply_find_msg() error: uninitialized symbol 'mask'.

ASoC: dmaengine: Make the pcm->name equal to pcm->id if the name is not set

2019-10-05T11:13:54+00:00

[ Upstream commit 2ec42f3147e1610716f184b02e65d7f493eed925 ] Some tools use the snd_pcm_info_get_name() to try to identify PCMs or for other purposes. Currently it is left empty with the dmaengine-pcm, in this case copy the pcm->id string as pcm->name. For example IGT is using this to find the HDMI PCM for testing audio on it.

ASoC: Intel: Haswell: Adjust machine device private context

2019-10-05T11:13:52+00:00

[ Upstream commit ca964edf0ddbfec2cb10b3d251d09598e7ca9b13 ] Apart from Haswell machines, all other devices have their private data set to snd_soc_acpi_mach instance. Changes for HSW/ BDW boards introduced with series: https://patchwork.kernel.org/cover/10782035/ added support for dai_link platform_name adjustments within card probe routines. These take for granted private_data points to snd_soc_acpi_mach whereas for Haswell, it's sst_pdata instead. Change private context of platform_device - representing machine board - to address this.

ASoC: fsl_ssi: Fix clock control issue in master mode

[ Upstream commit 696d05225cebffd172008d212657be90e823eac0 ] The test case is arecord -Dhw:0 -d 10 -f S16_LE -r 48000 -c 2 temp.wav & aplay -Dhw:0 -d 30 -f S16_LE -r 48000 -c 2 test.wav There will be error after end of arecord: aplay: pcm_write:2051: write error: Input/output error Capture and Playback work in parallel in master mode, one substream stops, the other substream is impacted, the reason is that clock is disabled wrongly. The clock's reference count is not increased when second substream starts, the hw_param() function returns in the beginning because first substream is enabled, then in end of first substream, the hw_free() disables the clock. This patch is to move the clock enablement to the place before checking of the device enablement in hw_param().

[ Upstream commit 0f6fc97501b790c971b11b52a654009d21c45238 ] Since hw_free() can be called multiple times and not just after a stop trigger command, we should check whether the RX or TX ready interrupt was truly enabled previously. For this, we assure that the condition of the wait event is always true, except when RX/TX interrupts are enabled.

ASoC: sun4i-i2s: Don't use the oversample to calculate BCLK

2019-10-05T11:13:43+00:00

[ Upstream commit 7df8f9a20196072162d9dc8fe99943f2d35f23d5 ] The BCLK divider should be calculated using the parameters that actually make the BCLK rate: the number of channels, the sampling rate and the sample width. We've been using the oversample_rate previously because in the former SoCs, the BCLK's parent is MCLK, which in turn is being used to generate the oversample rate, so we end up with something like this: oversample = mclk_rate / sampling_rate bclk_div = oversample / word_size / channels So, bclk_div = mclk_rate / sampling_rate / word_size / channels. And this is actually better, since the oversampling ratio only plays a role because the MCLK is its parent, not because of what BCLK is supposed to be. Furthermore, that assumption of MCLK being the parent has been broken on newer SoCs, so let's use the proper formula, and have the parent rate as an argument.
