Dan Carpenter 6967ddd378 PCI: dwc: Fix a 64bit bug in dw_pcie_ep_raise_msix_irq()
commit b5d1b4b46f856da1473c7ba9a5cdfcb55c9b2478 upstream.

The "msg_addr" variable is u64.  However, the "aligned_offset" is an
unsigned int.  This means that when the code does:

  msg_addr &= ~aligned_offset;

it will unintentionally zero out the high 32 bits.  Use ALIGN_DOWN() to do
the alignment instead.

Fixes: 2217fffcd63f ("PCI: dwc: endpoint: Fix dw_pcie_ep_raise_msix_irq() alignment support")
