Hi,
this one fixes initialisation of I2C/SPI nodes. Upon failure during intialisation, nodes were erroneously populated and never unmarked.
This lead to the problem that re-loaded drivers will never probe those devices again and can easily be fixed by clearing the OF_POPULATE flag when the node doesn't successfully initialise.
For the discussion of v1, see https://lkml.org/lkml/2016/10/14/483

changes since v1: - also fix I2C core driver - keep the atomic test-and-set, as Geert suggested
