2020-06-20iio: Move attach/detach of the poll func to the coreLars-Peter Clausen
All devices using a triggered buffer need to attach and detach the trigger to the device in order to properly work. Instead of doing this in each and every driver by hand move this into the core. At this point in time, all drivers should have been resolved to attach/detach the poll-function in the same order. This patch removes all explicit calls of iio_triggered_buffer_postenable() & iio_triggered_buffer_predisable() in all drivers, since the core handles now the pollfunc attach/detach. The more peculiar change is for the 'at91-sama5d2_adc' driver, since it's not immediately obvious that removing the hooks doesn't break anything. Eugen was able to test on at91-sama5d2-adc driver, sama5d2-xplained board. All seems to be fine.

2020-06-14iio: remove explicit IIO device parent assignmentAlexandru Ardelean
This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

2019-11-02iio: dln2-adc: fix iio_triggered_buffer_postenable() positionAlexandru Ardelean
The iio_triggered_buffer_postenable() hook should be called first to attach the poll function. The iio_triggered_buffer_predisable() hook is called last (as is it should). This change moves iio_triggered_buffer_postenable() to be called first. It adds iio_triggered_buffer_predisable() on the error paths of the postenable hook. For the predisable hook, some code-paths have been changed to make sure that the iio_triggered_buffer_predisable() hook gets called in case there is an error before it.
