[PATCH v3 0/3] hwmon: (ads7871) Modernize and fix DMA safety

[Tabrez Ahmed <tabreztalks@gmail.com>]

This series modernizes the ads7871 driver by migrating it to the
hwmon_device_register_with_info() API and moving the SPI transfer
buffer into the driver's private data structure to ensure it is
DMA-safe.

Changes in v3:
- Added Patch 1 to fix a pre-existing Endianness bug in the 16-bit
  register read logic, flagged by Sashiko AI during v2 review.
- Fixed multiple formatting and alignment issues caught by checkpatch
  --strict, as requested by Guenter.
- Added "While at it, fix checkpatch violations" to Patch 2 commit message.

Changes in v2:
- Dropped custom mutex in favor of native hwmon core serialization.
- Split API migration and DMA fix into separate, logical patches.
- Corrected output scaling and sign extension to meet hwmon ABI.
