- 2021-07-23 · [PATCH] NIU: fix incorrect error return, missed in previous revert · Paul Jakma <hidden>
Commit 7930742d6, reverting 26fd962, missed out on reverting an incorrect
change to a return value. The niu_pci_vpd_scan_props(..) == 1 case appears
to be a normal path - treating it as an error and return -EINVAL was
breaking VPD_SCAN and causing the driver to fail to load.
Fix, so my Neptune card works again.
