Unfortunately while this may fix the particular use-case on STM32, it breaks all other users as the 'gpio-line-names' property doesn't live on dev_fwnode(&gdev->dev) but on dev_fwnode(chip->parent). How about we first look for this property on the latter and only if it's not present descend down to the former fwnode?Oops, I have tested on x86 and it worked the same way. Lemme check this, but I think the issue rather in ordering when we apply fwnode to the newly created device and when we actually retrieve gpio-line-names property.
Hmm... I can't see how it's possible can be. Can you provide a platform name and pointers to the DTS that has been broken by the change? -- With Best Regards, Andy Shevchenko
