We could indeed use __func__ instead, that'd be fine. Looking at the code, there are also inconsistencies with the use of pr_err and dev_err. dev_err(bus->dev is wrong actually, this would use the bus variable assigned in the previous loop, this makes no sense for multi-segment topologies. Let's drop this patch and revisit all this, hope Vinod can deal with patch 1..4 otherwise we'll resend the set. Thanks Amadeusz for the feedback.
