Documentation: PCI: pci-endpoint: Fix EPF ops list

2024-07-09T22:59:02+00:00

With commit 5779dd0a7dbd7 ("PCI: endpoint: Use notification chain mechanism to notify EPC events to EPF") the linkup callback has been removed and replaced by EPC event notifications. With commit 256ae475201b1 ("PCI: endpoint: Add pci_epf_ops to expose function-specific attrs") a new (optional) add_cfs callback was added. Update documentation accordingly.

PCI: Use array for .id_table consistently

2024-06-07T19:46:12+00:00

While 'x' and '&x[0]' are equivalent, most of the PCI drivers use the former form for the .id_table. Update some drivers and documentation for consistency. Link: https://lore.kernel.org/r/20240517120458.1260489-1-masahiroy@kernel.org Signed-off-by: Masahiro Yamada Signed-off-by: Bjorn Helgaas
