[PATCH v11 00/10] lan966x pci device: Add support for SFPs, PCI part

[Herve Codina <herve.codina@bootlin.com>]

Hi,

Previously, I sent a big picture series adding support for SFP ports
available on the LAN966x PCI device [0].

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.
