PCI: dwc: Fix MSI-X EP framework address calculation bug
commit 15cb127e3c8f6232096d5dba6a5b4046bc292d70 upstream.
Fix an error caused by 3-bit right rotation on offset address
calculation of MSI-X table in dw_pcie_ep_raise_msix_irq().
The initial testing code was setting by default the offset address of
MSI-X table to zero, so that even with a 3-bit right rotation the
computed result would still be zero and valid, therefore this bug went
unnoticed.
