In this case the following may happen: 1. The "JACKDET rise" or ""JACKDET fall" IRQ triggers 2. arizona_jackdet runs and takes info->lock 3. The "HPDET" IRQ triggers 4. arizona_hpdet_irq runs, blocks on info->lock 5. arizona_jackdet calls arizona_stop_mic() and clears info->hpdet_done 6. arizona_jackdet releases info->lock 7. arizona_hpdet_irq now can continue running and: 7.1 Calls arizona_start_mic() (if a mic was detected) 7.2 sets info->hpdet_done Step 7 is undesirable / a bug: 7.1 causes the device to stay in a high power-state (with MICVDD enabled) 7.2 causes hpdet to not run on the next jack insertion, which in turn causes the EXTCON_JACK_HEADPHONE state to never get set This fixes both issues by skipping these 2 steps when arizona_hpdet_irq runs after the jack has been unplugged.

Before this commit arizona_extcon_remove() was doing several register writes to shut things down before disabling the IRQs and it was cancelling only 1 of the 3 different works used. Move all the register-writes shutting things down to after the disabling of the IRQs and add the 2 missing cancel_delayed_work_sync() calls. This fixes various possible races on driver unbind. One of which would always trigger on devices using the mic-clamp feature for jack detection. The ARIZONA_MICD_CLAMP_MODE_MASK update was done before disabling the IRQs, causing: 1. arizona_jackdet() to run 2. detect a jack being inserted (clamp disabled means jack inserted) 3. call arizona_start_mic() which: 3.1 Enables the MICVDD regulator 3.2 takes a pm_runtime_reference And this was all happening after the ARIZONA_MICD_ENA bit clearing, which would undo 3.1 and 3.2 because the ARIZONA_MICD_CLAMP_MODE_MASK update was being done after the ARIZONA_MICD_ENA bit clearing. So this means that arizona_extcon_remove() would exit with 1. MICVDD enabled and 2. The pm_runtime_reference being unbalanced. MICVDD still being enabled caused the following oops when the regulator is released by the devm framework: [ 2850.745757] ------------[ cut here ]------------ [ 2850.745827] WARNING: CPU: 2 PID: 2098 at drivers/regulator/core.c:2123 _regulator_put.part.0+0x19f/0x1b0 [ 2850.745835] Modules linked in: extcon_arizona ... ...

Note the probe (and remove) sequence is split into 2 parts: 1. The arizona_jack_codec_dev_probe() function inits a bunch of jack-detect specific variables in struct arizona_priv and tries to get a number of resources where getting them may fail with -EPROBE_DEFER. 2. Then once the machine driver has create a snd_sock_jack through snd_soc_card_jack_new() it calls snd_soc_component_set_jack() on the codec component, which will call the new arizona_jack_set_jack(), which sets up jack-detection and requests the IRQs. This split is necessary, because the IRQ handlers need access to the arizona->dapm pointer and the snd_sock_jack which are not available when the codec-driver's probe function runs. Note this requires that machine-drivers for codecs which are converted to use the new helper functions from arizona-jack.c are modified to create a snd_soc_jack through snd_soc_card_jack_new() and register this jack with the codec through snd_soc_component_set_jack().

The snd_soc_jack code will report the cable-type through both input_dev events and through ALSA controls and the button-presses through input_dev events. Note that this means that when the codec drivers are moved over to use the new arizona-jack.c library code instead of having a separate MFD extcon cell with the extcon-arizona.c driver, we will no longer report extcon events to userspace for cable-type changes. This should not be a problem since "standard" Linux distro userspace does not (and has never) used the extcon class interface for this. Android does have support for the extcon class interface, but that was introduced in the same release as support for input_dev cable-type events, so this should not be a problem for Android either. Note this also reduces ARIZONA_MAX_MICD_RANGE from 8 to 6, this is ok to do since this info is always provided through pdata (or defaults) and cannot be overridden from devicetree. All in kernel users of the pdata (and the fallback defaults) define 6 or less buttons/ranges.
