The result is the same but as I said in platform driver probe function will be called for each PCI controller. We don't want ISA is searched for more than once. Also please refer to V3 of this patch set in which I rebase them on latest tree. I made a non-recursive version of function to search for ISA under PCI nodes. -Hongtao. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
