Hi Hans,
For the extcon part, I sent the patch[1].
[1]https://git.kernel.org/cgit/linux/kernel/git/sre/linux-power-supply.git/commit/?h=for-next-next&id=3164eef74088d9603a16b97e574a4e0067da083a
Ok, I will cherry pick this one into my tree and rebase the patch-set
on top of it.
Regards,
Hans

Use devm_extcon_register_notifier and devm_power_supply_register
instead of their non devm counterparts, this avoids the need to do
manual cleanup and results in quite a nice code cleanup.
