This series addresses several issues in the ads7871 driver. It fixes an
architecture-dependent endianness bug in the 16-bit register read logic,
migrates the driver to the modern hwmon_device_register_with_info() API,
and moves the SPI transfer buffer into the driver's private data structure
to ensure DMA safety.

Note: I do not have access to the physical ADS7871 hardware. This
series has been compile-tested only.

Changes in v5:
- Fixed a bisectability issue where the <linux/unaligned.h> include 
  modernization was accidentally squashed into Patch 3 instead of Patch 1.
- Ensured the 1-byte SPI command write in ads7871_read_reg16() uses a 
  strictly typed 'u8' variable to prevent a Big-Endian pointer hazard.

Changes in v4:
- Patch 1: Refactored 16-bit register reads to use a dedicated 'u8' 
  transmit variable, eliminating a 32-bit pointer endianness hazard.

Changes in v3:
- Added Patch 1 to fix the pre-existing endianness bug in 16-bit reads.
- Fixed multiple formatting and alignment issues caught by checkpatch
  --strict, as requested by Guenter Roeck.
- Added "While at it, fix checkpatch violations" to Patch 2 commit message.
