I got a bug report for a DT node refcounting problem in the I2C subsystem. This
patch was a huge help in validating the bug report and the proposed solution.
So, I thought I bring it to attention again. Thanks Tyrel, for the initial
work!
Note that I did not test the dynamic updates, only of_node_{get|put} so far. I
read that Tyrel checked dynamic updates extensively with this patch. And since
DT overlays are also used within our Renesas dev team, this will help there, as
well.
Tested on a Renesas Salvator-XS board (R-Car H3).
Changes since RFC v1:
* rebased to v4.15-rc8
* fixed commit abbrev and one of the sysfs paths in commit desc
* removed trailing space and fixed pointer declaration in code
I consider all the remaining checkpatch issues irrelevant for this patch.
So what about applying it?
Kind regards,
Wolfram
