Thomas Gleixner e3c026be4d PCI/MSI: Remove over-zealous hardware size check in pci_msix_validate_entries() ... pci_msix_validate_entries() validates the entries array which is handed in by the caller for a MSI-X interrupt allocation. Aside of consistency failures it also detects a failure when the size of the MSI-X hardware table in the device is smaller than the size of the entries array. That's wrong for the case of range allocations where the caller provides the minimum and the maximum number of vectors to allocate, when the hardware size is greater or equal than the mininum, but smaller than the maximum. Remove the hardware size check completely from that function and just ensure that the entires array up to the maximum size is consistent. The limitation and range checking versus the hardware size happens independently of that afterwards anyway because the entries array is optional.
