[PATCH 0/8] iio: cleanup some new instances of manual parent setting.

[PATCH 0/8] iio: cleanup some new instances of manual parent setting.

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

It seems I still haven't trained my eyes to spot these.

I think they have all been introduced since
iio_device_alloc() and friends started setting this
8525df47b3d1e ("iio: core: fix/re-introduce back parent assignment")
78289b4a58b58 ("iio: core: pass parent device as parameter during allocation")

Anyhow, all seem fairly obvious to me, but maybe I missed something so please
take a look.

Unrelated to this series.
This looks like it could do without the of_node assignment as well.

I probably should have noticed this earlier.

Good point.  Rather than having a separate patch I'll pull that in here
whilst applying if no one shouts.

unrelated to this series, this dev_name(&pdev->dev) looks a bit weird;
this should resolve to the driver name AFAICT; which is "mt6360-adc"
it feels a bit off with respect to ABI; but maybe it's too late to change it?

Yup. We have some historical ones of these unfortunately when I wasn't
paying attention properly.  They are ABI for those parts now so
we can't fix them without significant risk of breaking someones platform.

Thanks for checking these.  I've added the of_node dropping bit
to the patch you pointed that out in.

Applied to the togreg branch of iio.git and pushed out as testing for
the autobuilders to poke at it and see if we missed anything!

Thanks,

Jonathan
