So it makes it 4, not 3 ;-) places where referencing platform_bus *maybe* makes some sense. Pawel

Seems fair enough to me. No, not at all, this is a different bus, put the root bus at the root of the sysfs tree, not at some "arbritrary" point on a platform device. > > diff --git a/drivers/char/tile-srom.c b/drivers/char/tile-srom.c > > index bd37747..4e4b7a2 100644 > > --- a/drivers/char/tile-srom.c > > +++ b/drivers/char/tile-srom.c > > @@ -350,7 +350,7 @@ static int srom_setup_minor(struct srom_dev *srom, int index) > > SROM_PAGE_SIZE_OFF, sizeof(srom->page_size)) < 0) > > return -EIO; > > > > - dev = device_create(srom_class, &platform_bus, > > + dev = device_create(srom_class, &platform_bus.dev, > > MKDEV(srom_major, index), srom, "%d", index); > > return PTR_ERR_OR_ZERO(dev); > > } > > Again, non-platform device placed in the hierarchy. Again, not ok. If it's a platform device, it's a platform device, and make it one.

Nope, see above :) thanks, greg k-h

I can't see any other way of getting the tree root, so an #ifdef it will be... Thanks for pointing this out! Pawe?

I think the author considers platform bus is understood as a representation of the MMIO space (and he's not alone). So then he wants to represent the physical hierarchy of the interconnect to get it in separate places in the /sys/devices/* tree. Whether it's a good thing to do or not, have no strong opinion, but can understand his approach.

Otherwise you could argue that all busses should belong under the platform bus as well, which isn't going to happen. > Whether it's a good thing to do or not, have no strong opinion, but can > understand his approach.

So it's not just simply a case of s/&platform_bus/NULL/ - maybe the function should fail when !dma_dev? I'll split the patch so each case is separate and post them to relevant maintainers. Pawel

There has been a lot of references to platform_bus device where it didn't make any sense, because simply using NULL as a parent will make the device be adopted by the top level anyway.
