2025-04-22iio: normalize array sentinel styleDavid Lechner
Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace the array sentinel in all IIO drivers to the same style. For some time, we've been trying to consistently use `{ }` (no trailing comma, no comment, one space between braces) for array sentinels in the IIO subsystem. Still nearly 50% of existing code uses a different style. To save reviewers from having to request this trivial change as frequently, let's normalize the style in all existing IIO drivers. At least when code is copy/pasted to new drivers, the style will be consistent.

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.

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.
