isn't needed there. Upatched code uses: memset(info, 0, sizeof(info)); where 'info' is a pointer and therefore only first 4 bytes of 'info' gets cleared on a 32bit machine. Anyway looking at the code zeoring this memory region isn't needed at all because the snd_emu10k1_fx8010_info() function initializes all the 'info' fields on its own. So that's why this code works at all in its original form. This patch removes this redundant code. Also snd_emu10k1_fx8010_info() can't fail so lets save some bytes and change its return type to void. Signed-off-by:

Update the documentation to reflect the last changes regarding the power-saving mode and register caches. Signed-off-by:

Added CONFIG_SND_HDA_POWER_SAVE kconfig. It's an experimental option to achieve an aggressive power-saving. With this option, the driver will turn on/off the power of each codec and controller chip dynamically on demand. The patch introduces a new module option 'power_save'. It specifies the second of time-out for automatic power-down. As default, it's 10 seconds. Setting 0 means to suppress the power-saving feature. The codec may have analog-input loopbacks, which are usually represented by mixer elements such as 'Mic Playback Switch' or 'CD Playback Switch'. When these are on, we cannot turn off the mixer and the codec chip has to be kept on. For bookkeeping these states, a new codec-callback is introduced. For the bus-controller side, a new callback pm_notify is introduced, which can be used to turn on/off the contoller appropriately. Note that this power-saving might cause slight click-noise at power-on/off. Also, it might take some time to wake up the codec, and might even drop some tones at the very beginning. This seems to be the side-effect of turning off the controller chip. This turn-off of the controller can be disabled by undefining HDA_POWER_SAVE_RESET_CONTOLLER in hda_intel.c. Signed-off-by:

Added snd_hda_codec_amp_stereo() function that changes both of stereo channels with the same mask and value bits. It simplifies most of amp-handling codes. Signed-off-by:

So far, the driver looked the table of snd_kcontrol_new used for creating mixer elements and forces to call each of its put callbacks in PM resume code. This is too ugly and hackish. Now, the resume is simplified using the codec amp and command register caches. The driver simply restores the values that have been written in the cache table. With this simplification, most codec support codes don't require any special resume callback. Signed-off-by:
-

This patch adds the cache for codec command registers. snd_hda_codec_write_cache() and snd_hda_sequence_write_cache() do the write operations with caching, which values can be resumed via snd_hda_codec_resume_cache(). The patch introduces only the framework, and no codec code is using this cache yet. It'll be implemented in the following patch. Signed-off-by:

Following the suggestion in this thread: https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/26683 the correct upper bound on desc[0] is 5 + num_ins not 6 + num_ins, because the index used later is 5+i, not 6+i. This change makes my Vosky Chatterbox speakerphone work. Apparently it also helps with the Minivox MV100. Signed-off-by:

In sound/pci/au88x0/au88x0.c::snd_vortex_create() : The Coverity checker found that if we allocate storage for 'chip' but then leave via the regions_out: label, then we end up leaking the storage allocated for 'chip'. I believe simply freeing 'chip' before the 'return err;' line is all we need to fix this, but please double-check me :) Signed-off-by:

As reported by Troy Heidner, the 'Gateway Solo 5150' laptop (for one) has an onboard ESS1879 that identifies itself through PNPBIOS as just that. He also confirmed that other than not knowing about it, snd-es18xx drives the chip fine, so this adds the ID to the driver. Signed-off-by:
