In this series patches touch several parts and sub-system in the kernel. Reviews have be done and it makes sense to split the series and send parts separately. This current series is the extraction of patches related to issues in the PCI subsystem. It has to be seen as a continuation of the big picture series but related to this specific core part. Patches 1 to 6 introduce and use fw_devlink_set_device() in already existing code. No functional change but the introduction of the fw_devlink_set_device() wrapper. Patch 7 avoids a dangling pointer. Patches 8 and 9 fix fw_devlink issues specific to PCI and the device-tree nodes created during enumeration. Patch 10 avoids the usage of np->data and adds guards to prevent incorrect nodes removal.
