Subject: [PATCH v1 0/1] i2c: Restore power status of device if probe fails

We have discovered that some power lines were always on even if the devices
on that power line was not used.

This happens because we failed to probe a device on the i2c bus, and the
ACPI Power Resource were never turned off.

This patch tries to fix this issue.
