Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:

Pre-existing issues:
- [High] Direct return on devm_thermal_of_zone_register failure skips critical error cleanup (PM leak and Use-After-Free).
- [High] Unbalanced disable_irq() on sun4i_prepare_for_irq() error path permanently disables the IRQ.

iio: adc: change from %ld to %pe for PTR_ERR() printing

This commit replaces numeric PTR_ERR() logging with the %pe format specifier.
The goal is to print error values in a more readable form.

[Severity: High]
This isn't a bug introduced by this patch, but returning directly here
skips the err_map cleanup label.

If devm_thermal_of_zone_register() fails with an error other than -ENODEV,
this code returns directly. Does this leave the device's runtime PM enabled
because the pm_runtime_disable() call in the err_map block is skipped?

Also, if the device was probed via sun4i_gpadc_probe_mfd(),
iio_map_array_register() was successfully called earlier:

drivers/iio/adc/sun4i-gpadc-iio.c:sun4i_gpadc_probe_mfd() {
    ...
    ret = iio_map_array_register(indio_dev, sun4i_gpadc_hwmon_maps);
    ...
}

By skipping iio_map_array_unregister() at the err_map label, does this
leave a dangling pointer in the global IIO maps pointing to indio_dev?
Since indio_dev is managed by devres (devm_iio_device_alloc), its memory
will be freed immediately upon probe failure. Could this result in a
use-after-free when another subsystem attempts to read from the map?

>  		}
>  	}

While reviewing this file, I also noticed another pre-existing regression in
sun4i_gpadc_read().

[Severity: High]
This is a pre-existing issue, but does the unbalanced disable_irq() on the
sun4i_prepare_for_irq() error path permanently disable the IRQ?

drivers/iio/adc/sun4i-gpadc-iio.c:sun4i_gpadc_read() {
    ...
    ret = sun4i_prepare_for_irq(indio_dev, channel, irq);
    if (ret)
        goto err;

    enable_irq(irq);
    ...
err:
    pm_runtime_put_autosuspend(indio_dev->dev.parent);
    disable_irq(irq);
    mutex_unlock(&info->mutex);
}

If sun4i_prepare_for_irq() fails, the code jumps to the err label and
unconditionally executes disable_irq(irq). Because enable_irq(irq) was never
reached, this increases the IRQ disable depth. 

Since the IRQs are initially requested with IRQF_NO_AUTOEN
(initial depth = 1), the unbalanced disable_irq() bumps the depth to 2.
On subsequent successful reads, enable_irq() will only decrement the depth
back to 1. Does this leave the IRQ permanently masked, causing
wait_for_completion_timeout() to continually time out?

Thanks for the change, but in the future, please slow down! Let the current
version sit for at least 24 hours before sending a new version so that
everyone has an opportunity to review it.

NAK (in this form). See below why.
Also note, the same applies to the similar cases in all patches like this.

This should be simply moved to dev_err_probe(). With that %pe will be
implied. Also it will save the time to move to dev_err_probe()
directly without any trampoline like this.

Further to this, when doing a change across a bunch of drivers, send one or two
as a test first to see what feedback you get.  You'd have gotten the reply from
Andy to such a patch without wasting as much of your time!
