Make sure to use codec->reg_def_copy instead of codec_drv->reg_cache_default wherever necessary. This change is necessary because in the next patch we move the cache initialization code outside snd_soc_register_codec() and by that time any data marked as __devinitconst such as the original reg_cache_default array might have already been freed by the kernel.

The snd_soc_codec_conf struct now holds codec specific configuration information. A new configuration option has been added to allow machine drivers to override the compression type set by the codec driver. In the absence of providing an snd_soc_codec_conf struct or when providing one but not setting the compress_type member to anything, the one supplied by the codec driver will be used instead. In all other cases the one set in the snd_soc_codec_conf struct takes effect. Signed-off-by:

Ensure that the base value of compress_type starts at 1 so that we know whether the machine driver has provided a compress_type for overriding the codec supplied one. Signed-off-by:

We need to keep a copy of the compress_type supplied by the codec driver so that we can override it if necessary with whatever the machine driver has provided us with. The reason for not modifying the codec->driver struct directly is that ideally we'd like to keep it const. Adjust the code in soc-cache and soc-core to make use of the compress_type member in the snd_soc_codec struct. Signed-off-by:

Blind copy of codec finding algorithm from soc_bind_dai_link does not work in soc_probe_aux_dev if matching codec name is not found. In that case the code falls through and tries to start the probing procedure with invalid codec pointer. Fix this and add an error print showing the codec name that cannot be found. Signed-off-by:

In alc5623_i2c_probe(), the default case for checking alc5623->id behaves the same as case 0x23. However, In alc5623_probe() the default case for checking alc5623->id becomes to be the same as case 0x21. This makes the meaning of default case inconsistent. Since we have checked codec id in alc5623_i2c_probe() by comparing vid2 with id->driver_data, it is not possible to run into the default case now. In case we may add more supported devices to alc5623_i2c_table in the future, this patch changes the default case return -EINVAL to let people know that they should not run into this case. They should also add a new case accordingly for the new id. Signed-off-by:

Current FSI driver was checking register range on fsi_master_xxx function. This runtime check was added to avoid an illegal access from wrong/mistake implementation. But it is useless check under the correct implementation. This patch escape runtime check by using macro technique. If there is wrong implementation, it will be compile error. Signed-off-by:

We shouldn't be assigning to the driver structure (which really ought to be const, further patch to follow) though there's unlikely to be any actual problem except in the unlikely case that two devices with the same driver but different bus types appear in the same system. Signed-off-by:

Commit 2eea392d "ASoC: Add support for optional auxiliary dailess codecs" causes a build failure in soc-core.c: soc_probe_aux_dev since code tries to access non-existing struct snd_soc_dapm_context and struct snd_soc_card members. Root cause for this was a double accident. Author sent the RFC patch from top of another patch set and the RFC got committed. Fix the build failure by removing the code line that depends on that another patch set. Signed-off-by:

This makes possible to register auxiliary dailess codecs in a machine driver. Term dailess is used here for amplifiers and codecs without DAI or DAI being unused. Dailess auxiliary codecs are kept in struct snd_soc_aux_dev and those codecs are probed after initializing the DAI links. There are no major differences between DAI link codecs and dailess codecs in ASoC core point of view. DAPM handles them equally and sysfs and debugfs directories for dailess codecs are similar except the pmdown_time node is not created. Only suspend and resume functions are modified to traverse all probed codecs instead of DAI link codecs. Example below shows a dailess codec registration. struct snd_soc_aux_dev foo_aux_dev[] = { { .name = "Amp", .codec_name = "codec.2", .init = foo_init2, }, }; static struct snd_soc_card card = { ... .aux_dev = foo_aux_dev, .num_aux_devs = ARRAY_SIZE(foo_aux_dev), }; Signed-off-by: -

The bitmap_zero() nbits argument was improperly set to reg_size but the underlying buffer was bmp_size long. This caused the memset to zero past the end of the allocated buffer and into the kernel heap causing strange kernel crashes sometimes by overwriting critical kernel structures. Signed-off-by:

In nuc900_dma_hw_params(), if snd_pcm_lib_malloc_pages failed it returns without calling spin_unlock_irqrestore(). Since snd_pcm_lib_malloc_pages() does not touch struct nuc900_audio, we don't need to hold the lock while calling snd_pcm_lib_malloc_pages(). Fix it by moving spin_lock_irqsave() down to after snd_pcm_lib_malloc_pages(). In nuc900_dma_prepare(), spin_unlock_irqrestore() is missing in the error path. Fix it by removing the return in default case. Signed-off-by:
