Now that we have a get_match_data() callback as part of the firmware node, implement the OF specific piece for it. Signed-off-by: Sinan Kaya <redacted> --- drivers/of/property.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+)

I see a check for the matches argument but not for the node argument. Am I missing something?

I can fix this.
of_device_get_match_data() already does most of this, but getting a device ptr from fwnode_handle may not be possible?
I couldn't figure out how to do that. Do you have a suggestion? I have been looking for examples with no luck.
