2025-04-22iio: normalize array sentinel styleDavid Lechner1-2/+2
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.

2022-11-23iio: common: scmi_iio: do not use internal iio_dev lockNuno Sá1-2/+7
The iio_device lock is only meant for internal use. Hence define a device local lock to protect against concurrent accesses. While at it, properly include "mutex.h" for mutex related APIs.

2022-04-10iio: core: Simplify the registration of kfifo buffersMiquel Raynal1-1/+0
Among all the users of the kfifo buffers, no one uses the INDIO_BUFFER_HARDWARE mode. So let's take this as a general rule and simplify a little bit the internals - overall the documentation - by eliminating unused specific cases. Use the INDIO_BUFFER_SOFTWARE mode by default with kfifo buffers, which will basically mimic what all the "non direct" modes do.
