+static const struct of_device_id bd71837_of_match[] = { + { .compatible = "rohm,bd71837", .data = (void *)0}, + { },nit: { /* sentinel */ }I am sorry but I didn't quite get the point here. Could you please explain what did you expect to be added here?It's a nit but It is a good practice to specify that the last entry is a sentinel. Just this. +static const struct of_device_id bd71837_of_match[] = { + { .compatible = "rohm,bd71837", .data = (void *)0}, + { /* sentinel */ } +};Oh, I see. Finally something I can disagree =) I quickly opened few random drivers which declare match table. None of them practiced this good practice. So I guess it is not such a standard after all. And I guess the meaning of last entry in match table should be quite obvious. Adding the comment /* sentinel */ sounds like stating the obvious at best - at worst it gets one just to wonder what the "sentinel" means =)
git grep "/\* sentinel \*/" Anyway, I marked this change as a nit, so you don't need to change. I just commented because at some point I received a "complain" when I didn't add it. But this is up to the maintainer and I am not sure if the "complain" was received in this subsystem :) Cheers, Enric

And just noticed, is .data = (void *)0 really required?As static structs should be initialized to zero I'd say it is not required. Will remove this. Thanks for pointing this out. Br, Matti Vaittinen
