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.

For more information about the product, see:
https://github.com/pinefeat/cef168

Changes in v4:
 - removed driver mention from the hardware documentation;
 - added named email in commit signed-off-by;
 - added select CRC8 in Kconfig;
 - removed header file;
 - moved variable declaration at the beginning of the function;
 - removed kerneldoc from structures;
 - removed control id check as the core handles this for us;
 - removed Power Management Runtime (pm_runtime_*) calls as redundant;
 - reserved v4l2 controls in linux header file;

You already sent v4, so this makes a duplicate posting messing up with
tools.

Each posting is its own version. Resending - not marked here as resend -
would be sending the same patch.

Best regards,

Gentle ping.

This is still v4; the only difference was correcting the sender address.
No functional changes since v4. I'm keeping this as v4 unless you prefer a
rebase.
