[PATCH AUTOSEL 5.4 105/350] iio: chemical: atlas-ph-sensor: fix iio_triggered_buffer_predisable() position

[Sasha Levin]

From: Alexandru Ardelean <alexandru.ardelean@xxxxxxxxxx>

[ Upstream commit 0c8a6e72f3c04bfe92a64e5e0791bfe006aabe08 ]

The iio_triggered_buffer_{predisable,postenable} functions attach/detach
the poll functions.

The iio_triggered_buffer_predisable() should be called last, to detach the
poll func after the devices has been suspended.

The position of iio_triggered_buffer_postenable() is correct.

Note this is not stable material. It's a fix in the logical
model rather fixing an actual bug.  These are being tidied up
throughout the subsystem to allow more substantial rework that
was blocked by variations in how things were done.
