The patch c358e640 "ASoC: soc-cache: Add trace event for snd_soc_cache_sync()" introduced a dereference of "codec->cache_ops" before we had checked it for NULL. I pulled the check forward, and then pulled everything in an indent level. Signed-off-by:

The wm8753 codec supports switching between different DAI modes. The current drivers tries to implement this by changing the DAI driver at runtime. But to properly work this would require support from the ASoC core. So this patch takes a different approch on how the DAI mode switching is implemented. The only difference, from a driver point of view, between the different DAI modes is how to program the DAI format to the hardware. So what this patch is, it stores the current format for each DAI in the drivers private struct and when the DAI mode is changed the format gets simply reprogrammed according to the new DAI mode. Futhermore this patch restricts the changing of the DAI format to when the codec is inactive. Signed-off-by:

On WM8994 revision D and earlier ensure optimal sequencing with simultaneous usage of AIF1 and AIF2 by tying the signals together so if paths through both are connected the streams are started simultaneously. Signed-off-by:

Due to the different routing for AIF1 and AIF2 we weren't using a single widget to represent the ADCDAT signal. For consistency add one. Signed-off-by:

McASP1 is used on the DA830/OMAP-L137 platform for the codec. This is different from the DA850/OMAP-L138 platform which uses McASP0. This is fixed by adding a new snd_soc_dai_link struct. Signed-off-by:

The .card member of the snd_soc_pcm_runtime structure pointed to by the snd_soc_dai_link.init() argument used to be initialized before the function being called. This has changed, probably unintentionally, after recent refactorings. Since the function implementations are free to make use of this pointer, move its assignment back before the function is called to avoid NULL pointer dereferences.

For some codecs with large register maps, it was not possible to dump all registers via the codec_reg file but only up to PAGE_SIZE bytes. This patch fixes this problem. Signed-off-by:

Make the format of the codec_reg file more easily parsable. Remove the header field which gives the codec name. These changes are important when it comes to extend the debugfs codec_reg file to dump more than PAGE_SIZE bytes to make it easier to calculate offsets within the file. We still need to handle the case when the snd_soc_read() call fails and <no data: %d> is outputted. Signed-off-by:

The CX20442 codec driver never provided the snd_soc_codec_driver's .reg_cache_default member. With the latest ASoC framework changes, it seems to be referred unconditionally, resulting in a NULL pointer dereference if missing. Provide it.

The Amstrad Delta ASoC driver used to override the digital_mute() callback, expected to be not provided by the on-board CX20442 CODEC driver, with its own implementation. While this is still posssible when substituting the whole empty snd_soc_dai_driver.ops member (the CX20442 case), replacing snd_soc_dai_ops.digital_mute only is no longer correct after the snd_soc_dai_driver.ops member has been constified, and results in build error. Drop this actually not used code path in hope the CX20442 driver never provides its own snd_soc_dai_ops structure. Created and tested against linux-2.6.38-rc2 Signed-off-by:

Earphone in Nokia RX-51/N900 is connected to left HP output of B part of the TLV320AIC34 dual codec. In RX-51 the codec A is used as a traditional codec and the codec B as an auxiliary device. Audio from codec A goes via the codec B to earphone: MONO_LOUT of A -> LINE2R of B (B interconnects) -> HPLOUT of B -> Earphone. Take earphone into use by utilizing the recent ASoC auxiliary and cross-device support. Signed-off-by:

Add DAPM widget definitions for the internal speaker paths. Currently, this path is always enabled while playback is active. Add code to control the speaker amplifier GPIO. The GPIO is requested during _init, since that's the first time it is guaranteed that the WM8903 module is loaded, probed, and hence has exported its GPIO chip. Signed-off-by:

Previously, snd-soc-tegra-harmony internally instantiated a platform device object whenever the module was loaded. Instead, switch to a more typical model where arch/arm/mach-tegra defines a platform device, and snd-soc-tegra-harmony acts as a driver for such a platform device. Define a new struct tegra_harmony to store driver data in the future. Signed-off-by:

All ASoC cards need snd_soc_initialize_card_lists called. Previously, it was only called for cards backed by a "soc-audio" platform device, via soc_probe(). However, it's also needed for cards backed by other platform devices, and registered directly via snd_soc_register_card(). Signed-off-by:

snd_soc_dapm_put_volsw() has variables for both the unshifted and shifted mask for updates commit 97404f (ASoC: Do DAPM control updates in the middle of DAPM sequences) got confused between the two of these. Since there's no need to keep a copy of the unshifted mask fix this and simplify the code by using only one mask variable.
