From d93f8399053dcf117ff56a3029ff08c0e36f4b75 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Krzysztof=20Wilczy=C5=84ski?= Date: Fri, 16 Apr 2021 20:58:40 +0000 Subject: PCI/sysfs: Convert "vpd" to static attribute MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 . 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 Based-on: https://lore.kernel.org/r/7703024f-8882-9eec-a122-599871728a89@gmail.com Based-on-patch-by: Heiner Kallweit Link: https://lore.kernel.org/r/20210416205856.3234481-5-kw@linux.com Signed-off-by: Krzysztof Wilczyński Signed-off-by: Bjorn Helgaas --- drivers/pci/pci-sysfs.c | 15 +-------------- 1 file changed, 1 insertion(+), 14 deletions(-) (limited to 'drivers/pci/pci-sysfs.c') diff --git a/drivers/pci/pci-sysfs.c b/drivers/pci/pci-sysfs.c index c469d9cad0a8..6dc01fe21fd2 100644 --- a/drivers/pci/pci-sysfs.c +++ b/drivers/pci/pci-sysfs.c @@ -1378,12 +1378,6 @@ static const struct attribute_group pci_dev_reset_attr_group = { .is_visible = pci_dev_reset_attr_is_visible, }; - -static void pci_create_capabilities_sysfs(struct pci_dev *dev) -{ - pcie_vpd_create_sysfs_dev_files(dev); -} - int __must_check pci_create_sysfs_dev_files(struct pci_dev *pdev) { int retval; @@ -1395,18 +1389,11 @@ int __must_check pci_create_sysfs_dev_files(struct pci_dev *pdev) if (retval) return retval; - /* add sysfs entries for various capabilities */ - pci_create_capabilities_sysfs(pdev); pci_create_firmware_label_files(pdev); return 0; } -static void pci_remove_capabilities_sysfs(struct pci_dev *dev) -{ - pcie_vpd_remove_sysfs_dev_files(dev); -} - /** * pci_remove_sysfs_dev_files - cleanup PCI specific sysfs files * @pdev: device whose entries we should free @@ -1418,7 +1405,6 @@ void pci_remove_sysfs_dev_files(struct pci_dev *pdev) if (!sysfs_initialized) return; - pci_remove_capabilities_sysfs(pdev); pci_remove_resource_files(pdev); pci_remove_firmware_label_files(pdev); } @@ -1514,6 +1500,7 @@ const struct attribute_group *pci_dev_groups[] = { &pci_dev_config_attr_group, &pci_dev_rom_attr_group, &pci_dev_reset_attr_group, + &pci_dev_vpd_attr_group, NULL, }; -- cgit v1.2.3
