Hi Greg,

I maintain this driver now and my pull requests usually go through
Wolfram's i2c tree (Cc'ed). I initially intended for this series to be
applied for 4.18. For 4.17 luckily the only other changes for at24 are
device tree bindings, so I guess we can keep it in misc-char, since
there are no conflicts.

Let me resend the corrected patch 4.

Best regards,
Bartosz Golaszewski
