So whenever I prepare a new revision, collected acks, sobs are chronological, but end up before my sob. But since you are the second maintainer which has objection to that style I probably should change that... >> --- >> drivers/mfd/rn5t618.c | 10 +++++++--- >> 1 file changed, 7 insertions(+), 3 deletions(-) >> >> diff --git a/drivers/mfd/rn5t618.c b/drivers/mfd/rn5t618.c >> index 7607ced..d9b4d40 100644 >> --- a/drivers/mfd/rn5t618.c >> +++ b/drivers/mfd/rn5t618.c >> @@ -103,9 +103,13 @@ static int rn5t618_i2c_probe(struct i2c_client *i2c, >> return ret; >> } >> >> - if (!pm_power_off) { >> - rn5t618_pm_power_off = priv; >> - pm_power_off = rn5t618_power_off; >> + if (of_device_is_system_power_controller(i2c->dev.of_node)) { >> + if (!pm_power_off) { >> + rn5t618_pm_power_off = priv; >> + pm_power_off = rn5t618_power_off; >> + } else { >> + dev_err(&i2c->dev, "Failed to set poweroff capability, already defined\n"); > > This is not an error.

FWIW, I copied the code (and that message) from here, where dev_err is probably also not appropriate: drivers/regulator/act8865-regulator.c > Also, is this message actually accurate? Your commit message would > indicate that it's not. Hm, maybe we should bail out with an error in that case since DT explicitly asks to be power controller...
