Subject: [PATCH v2 0/2] spi, i2c: mark device nodes only in case of successful instantiation
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
Ralf
changes since v1:
- also fix I2C core driver
- keep the atomic test-and-set, as Geert suggested
