Currently the call of kill_fasync() from an interrupt handler might lead to potential spin deadlocks, as spotted by syzkaller. Unfortunately, it's not so trivial to fix this lock chain as it's involved with the tasklist_lock that is touched in allover places. As a temporary workaround, this patch provides the way to defer the async signal notification in a work. The new helper functions, snd_fasync_helper() and snd_kill_faync() are replacements for fasync_helper() and kill_fasync(), respectively. In addition, snd_fasync_free() needs to be called at the destructor of the relevant file object. Link: https://lore.kernel.org/r/20220728125945.29533-2-tiwai@suse.deSigned-off-by:

This reverts commit 980b3a87. The commit didn't consider the fact that ASoC hdac-hda driver initializes the HD-audio stuff without calling snd_hda_codec_device_init(). Hence this caused a regression leading to Oops. Revert the commit to restore the behavior.

This is required to support CS35L41 calibration. By default, speaker protection firmware will be loaded, if available. However, different firmware is required to run the calibration sequence, so it is necessary to add support to be able to unload, switch and reload firmware. This patch adds 2 ALSA Controls for each amp: "DSP1 Firmware Load" "DSP1 Firmware Type" "DSP1 Firmware Load" can be used to unload and load the firmware. "DSP1 Firmware Type" can be used to switch the target firmware to be loaded by "DSP1 Firmware Load" Since loading firmware can add new ALSA controls, it is necessary to ensure the firmware loading is run asynchronously from the ALSA control itself to prevent deadlocks. Note: When switching between firmwares, an ALSA control is only added if it has not previously existed. If it had existed previously, it will be re-enabled instead. Signed-off-by:

The config sequences for running with and without firmware and DSP are different. The original behavior assumed that we would only run without DSP only in the case where firmware load failed. This meant the non-firmware sequence was written with the assumtion that various registers would be set to their default value. However, to support the ability to unload the firmware, the non-firmware register sequence must be updated to update all required registers, including values that would be defaulted, in case the firmware sequence, which could have already run, has changed their value.

Merge tag 'asoc-v5.20' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v5.20 This is a big release thus far and there will probably be more changes to come, it's a combination of a larger than usual crop of new drivers and some subsysetm wide cleanups from Charles rather than anything structural. The SOF and Intel DSP code both also continue to be very actively developed. - Restructing of the set_fmt() callbacks to be specified in terms of the device rather than with semantics depending on if the device is supposed to be a CODEC or SoC, making things clearer in situations like CODEC to CODEC links. - Clean up of the way we flag which DAI naming scheme we use to reflect the progress that's been made modernising things. - Merge of more of the Intel AVS driver stack, including some board integrations. - New version 4 mechanism for communication with SOF DSPs. - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms. - Improvements for CODEC to CODEC support in the generic cards. - Support for AMD Jadeite and various machines, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780.

There are two bugs that have to do with when we copy the payload: size = simple_write_to_buffer(ipc4_msg->data_ptr, priv->max_msg_size, ppos, buffer, count); The value of "*ppos" was supposed to be zero but it is sizeof(ipc4_msg->header_u64) so it will copy the data into the middle of the "ipc4_msg->data_ptr" buffer instead of to the start. The second problem is "buffer" should be "buffer + sizeof(ipc4_msg->header_u64)". This function is used for fuzz testing so the data is normally random and this bug likely does not affect anyone very much. In this context, it's simpler and more appropriate to use copy_from_user() instead of simple_write_to_buffer() so I have re-written the function.
