This series converts dev_err() calls to dev_err_probe() in the probe
paths of various IIO ADC drivers. This ensures proper handling of
deferred probing and simplifies error handling.

Where needed, a local struct device pointer is introduced first to
reduce repeated &spi->dev dereferences throughout the probe function.

Drivers addressed:
  - ad7949, ad7780, ad7793, ad7292, ad7791, ad7280a, ad7768-1,
    ad9467, ad4062
