When sm5502_init_dev_type() iterates over sm5502_reg_data to

There is no need to add another empty element to sm5502_reg_data.
Having the additional empty element in sm5502_reg_data will just
result in writing 0xff to register 0x00, which does not really

[ Upstream commit e5b499f6fb17bc95a813e85d0796522280203806 ]
We must free/disable all interrupts and cancel all pending works
before doing further cleanup.
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 ]------------

[ Upstream commit c309a3e8793f7e01c4a4ec7960658380572cb576 ]
When the jack is partially inserted and then removed again it may be
removed while the hpdet code is running. 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.
