What about replacing the int nvme_get_pci_ids(struct libnvme_global_ctx *ctx,
struct libnvme_transport_handle *hdl,
__u32 *vid, __u32 *did,
__u32 *subsys_vid, __u32 *subsys_did,
__u32 *class_code);more common code and works also on windows... |

Remove the WDC-local wdc_get_pci_ids() implementation and replace all 13 call sites with the new common nvme_get_pci_ids() introduced in nvme-pci-ids.h. The new function implements the same sysfs-based PCI ID lookup but works cross-platform (including Windows) and is shared across plugins. Note the argument order change: wdc_get_pci_ids() took (*ctx, *hdl, *device_id, *vendor_id) while nvme_get_pci_ids() takes (*ctx, *hdl, *vid, *did, *subsys_vid, *subsys_did, *class_code). The three unused output parameters are passed as NULL. No functional change intended. Signed-off-by: Sarah Ahmed <sarah.ahmed@ibm.com>

After successfully reading the vendor sysfs file, ret is assigned 0, but this value is never read. The variable is
unconditionally overwritten by the subsequent read() call for the device ID file before it is used again.
Remove the dead assignment. No functional change.
