Nouveau - Mar 2020 - [PATCH 0/6] gpu: convert to use new I2C API

We are deprecating calls which return NULL in favor of new variants which
return an ERR_PTR. Only build tested.


Wolfram Sang (6):
  drm/amdgpu: convert to use i2c_new_client_device()
  drm/gma500: convert to use i2c_new_client_device()
  drm/i2c/sil164: convert to use i2c_new_client_device()
  drm/i2c/tda998x: convert to use i2c_new_client_device()
  drm/nouveau/therm: convert to use i2c_new_client_device()
  drm/radeon: convert to use i2c_new_client_device()

Move away from the deprecated API and return the shiny new ERRPTR where
useful.

With the ack from Alex I went ahead and applied the patches to
drm-misc-next.
