Dear Maintainer,

please enable

  CONFIG_MFD_DLN2=m
  CONFIG_GPIO_DLN2=m
  CONFIG_DLN2_ADC=m
  CONFIG_I2C_DLN2=m
  CONFIG_SPI_DLN2=m

to add support for the Diolan  DLN-2 USB-I2C/SPI/GPIO Adapter, see
https://diolan.com/dln2. Most major distributions support it in their current
versions, e.g., Fedora, OpenSUSE, Arch, Ubuntu.

It would be greatly appreciated.

Thanks,
Gero
