The "vpd" sysfs attribute allows access to Vital Product Data (VPD). Previously it was dynamically created either by pci_bus_add_device() or the pci_sysfs_init() initcall, but since it doesn't need to be created or removed dynamically, we can use a static attribute so the device model takes care of addition and removal automatically. Convert "vpd" to a static attribute and use the .is_bin_visible() callback to check whether the device supports VPD. Remove pcie_vpd_create_sysfs_dev_files(), pcie_vpd_remove_sysfs_dev_files(), pci_create_capabilities_sysfs(), and pci_create_capabilities_sysfs(), which are no longer needed. [bhelgaas: This is substantially the same as the earlier patch from Heiner Kallweit <hkallweit1@gmail.com>. I included Krzysztof's change here so all the "convert to static attribute" changes are together.] [bhelgaas: rename to vpd_read()/vpd_write() and pci_dev_vpd_attr_group] Suggested-by: Oliver O'Halloran <oohall@gmail.com> Based-on: https://lore.kernel.org/r/7703024f-8882-9eec-a122-599871728a89@gmail.com Based-on-patch-by: Heiner Kallweit <hkallweit1@gmail.com> Link: https://lore.kernel.org/r/20210416205856.3234481-5-kw@linux.com Signed-off-by: Krzysztof Wilczyński <kw@linux.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |
