Some powers were changed during the jack insert detection and clk's enable/disable in CCF. If in parallel, the influence has a chance to detect the wrong jack type. We refer to the below commit of the variant codec (rt5682) to fix this issue. ASoC: rt5682: Fix deadlock on resume 1. Remove rt5682s_headset_detect in rt5682s_jd_check_handler and use jack_detect_work instead of. 2. Use dapm mutex used in CCF to protect most of jack_detect_work.

One or both of those has to be renamed or they need to be merged into one thing." Fix the duplicated control name by combining the two SPDIF controls here and move the register bits onto the DAPM widget and have DAPM control them.

When parsing the compressed stream the whole buffer descriptor is now read in a single cs_dsp_coeff_read_ctrl; on older firmwares this descriptor is just 4 bytes but on more modern firmwares it is 24 bytes. The current code reads the full 24 bytes regardless, this was working but reading junk for the last 20 bytes. However commit f444da38 ("firmware: cs_dsp: Add offset to cs_dsp read/write") added a size check into cs_dsp_coeff_read_ctrl, causing the older firmwares to now return an error. Update the code to only read the amount of data appropriate for the firmware loaded.

In commit da0363f7 ("ASoC: qcom: Fix for DMA interrupt clear reg overwriting") we changed regmap_write() to regmap_update_bits() so that we can avoid overwriting bits that we didn't intend to modify. Unfortunately this change breaks the case where a register is writable but not readable, which is exactly how the HDMI irq clear register is designed (grep around LPASS_HDMITX_APP_IRQCLEAR_REG to see how it's write only). That's because regmap_update_bits() tries to read the register from the hardware and if it isn't readable it looks in the regmap cache to see what was written there last time to compare against what we want to write there. Eventually, we're unable to modify this register at all because the bits that we're trying to set are already set in the cache. This is doubly bad for the irq clear register because you have to write the bit to clear an interrupt. Given the irq is level triggered, we see an interrupt storm upon plugging in an HDMI cable and starting audio playback. The irq storm is so great that performance degrades significantly, leading to CPU soft lockups. Fix it by using regmap_write_bits() so that we really do write the bits in the clear register that we want to. This brings the number of irqs handled by lpass_dma_interrupt_handler() down from ~150k/sec to ~10/sec.

The current rt5682_jack_detect_handler() assumes the component and card will always show up and implements an infinite usleep loop waiting for them to show up. This does not hold true if a codec interrupt (or other event) occurs when the card is unbound. The codec driver's remove or shutdown functions cannot cancel the workqueue due to the wait loop. As a result, code can either end up blocking the workqueue, or hit a kernel oops when the card is freed. Fix the issue by rescheduling the jack detect handler in case the card is not ready. In case card never shows up, the shutdown/remove/suspend calls can now cancel the detect task.

This reverts commit 9de2b928 ("ASoC: mediatek: Check for error clk pointer"). With this patch in the tree, Chromebooks running the affected hardware no longer boot. Bisect points to this patch, and reverting it fixes the problem. An analysis of the code with this patch applied shows: ret = init_clks(pdev, clk); if (ret) return ERR_PTR(ret); ... for (j = 0; j < MAX_CLKS && data->clk_id[j]; j++) { struct clk *c = clk[data->clk_id[j]]; if (IS_ERR(c)) { dev_err(&pdev->dev, "%s: clk unavailable\n", data->name); return ERR_CAST(c); } scpd->clk[j] = c; } Not all clocks in the clk_names array have to be present. Only the clocks in the data->clk_id array are actually needed. The code already checks if the required clocks are available and bails out if not. The assumption that all clocks have to be present is wrong, and commit 9de2b928 ("ASoC: mediatek: Check for error clk pointer") needs to be reverted.

When writing out a stereo control we discard the change notification from the first channel, meaning that events are only generated based on changes to the second channel. Ensure that we report a change if either channel has changed.

Since the commit in the Fixes tag below, 'wm->input_dev' is a managed resource that doesn't need to be explicitly unregistered or freed (see devm_input_allocate_device() documentation) So, remove some unless line of code to slightly simplify it.

The controls allow inputs to be specified as negative but our manipulating them into register fields need to be done on unsigned variables so the checks for negative numbers weren't taking effect properly. Do the checks for negative values on the variable in the ABI struct rather than on our local unsigned copy.

On resume from suspend the following chain of events can happen: A rt5682_resume() -> mod_delayed_work() for jack_detect_work B DAPM sequence starts ( DAPM is locked now) A1. rt5682_jack_detect_handler() scheduled - Takes both jdet_mutex and calibrate_mutex - Calls in to rt5682_headset_detect() which tries to take DAPM lock, it starts to wait for it as B path took it already. B1. DAPM sequence reaches the "HP Amp", rt5682_hp_event() tries to take the jdet_mutex, but it is locked in A1, so it waits. Deadlock. To solve the deadlock, drop the jdet_mutex, use the jack_detect_work to do the jack removal handling, move the dapm lock up one level to protect the most of the rt5682_jack_detect_handler(), but not the jack reporting as it might trigger a DAPM sequence. The rt5682_headset_detect() can be changed to static as well.

Correct size of iec_status array by changing it to the size of status array of the struct snd_aes_iec958. This fixes out-of-bounds slab read accesses made by memcpy() of the hdmi-codec driver. This problem is reported by KASAN.

The recent fix for DPCM locking also covered the loop in dpcm_be_disconnect() with the FE stream lock. This caused an unexpected side effect, thought: calling debugfs_remove_recursive() in the spinlock may lead to lockdep splats as the code there assumes the SOFTIRQ-safe context. For avoiding the problem, this patch changes the disconnection procedure to two phases: at first, the matching entries are removed from the linked list, then the resources are freed outside the lock.

The recent change for DPCM locking caused spurious lockdep warnings. Actually the warnings are false-positive, as those are triggered due to the nested stream locks for FE and BE. Since both locks belong to the same lock class, lockdep sees it as if a deadlock. For fixing this, we need to take PCM stream locks for BE with the nested lock primitives. Since currently snd_pcm_stream_lock*() helper assumes only the top-level single locking, a new helper function snd_pcm_stream_lock_irqsave_nested() is defined for a single-depth nested lock, which is now used in the BE DAI trigger that is always performed inside a FE stream lock.
