Pull i2c updates from Wolfram Sang:
 "This removes the currently unused CLASS_DDC support (controllers set
  the flag, but there is no client to use it).

  Also, CLASS_SPD support gets simplified to prepare removal in the
  future. Class based instantiation is not recommended these days
  anyhow.

  Furthermore, I2C core now creates a debugfs directory per I2C adapter.
  Current bus driver users were converted to use it.

  Finally, quite some driver updates. Standing out are patches for the
  wmt-driver which is refactored to support more variants.

  This is the rebased pull request where a large series for the
  designware driver was dropped"

drm/amd/pm: Remove I2C_CLASS_SPD support

2024-01-18T20:10:41+00:00

I2C_CLASS_SPD was used to expose the EEPROM content to user space,
via the legacy eeprom driver. Now that this driver has been removed,
we can remove I2C_CLASS_SPD support. at24 driver with explicit
instantiation should be used instead.
