Subject: [PATCH v3 0/2] Pinefeat cef168 lens control board driver

This patch series adds support for the Pinefeat adapter, which interfaces
Canon EF and EF-S lenses to non-Canon camera bodies. The cef168 circuit
control board provides an I2C interface for electronic focus and aperture
control. The driver integrates with the V4L2 sub-device API.

Changes in v3:
 - removed vcc-supply property and example
 - fixed incorrect type in assignment
