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.

2024-08-03iio: dac: mcp4728: use devm_regulator_get_enable_read_voltage()David Lechner
This makes use of the new devm_regulator_get_enable_read_voltage() helper function to reduce boilerplate code in the MCP4728 DAC driver.

2024-08-03iio: dac: mcp4728: rename err to ret in probe functionDavid Lechner
To prepare for using a function that returns a non-error value, rename the variable 'err' to 'ret' in the probe function.

2024-05-27iio: Drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.
