[PATCH v4 00/12] iio: use dev_err_probe in probe path for ADI drivers

[Antoniu Miclaus <antoniu.miclaus@analog.com>]

Use dev_err_probe() consistently in the probe path of several ADI IIO
drivers. This simplifies error handling and ensures proper logging of
deferred probes.

Each driver is updated in two patches: first introducing a local
struct device *dev variable alongside the existing spi variable to
replace &spi->dev references in non-error paths, then converting
dev_err() error paths to use dev_err_probe().

Drivers updated:
 - adrf6780
 - admv1014
 - admv1013
 - adf4377
 - ad7293
 - admv8818

Changes in v4:
 - Split each driver update back into two separate patches: one for
   introducing the struct device variable and one for the dev_err_probe()
   conversion. No lines are edited twice cross patch pairs, error-only
   functions get dev introduced in the "use dev_err_probe" commit.
