[PATCH v2 0/2] spi, i2c: mark device nodes only in case of successful instantiation

[Ralf Ramsauer <ralf@xxxxxxxxxxxxxxxxxxxxxx>]

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

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