We already clear all the other interrupts (ISR0, ISR1, HOST_CTRL_INT).
Define a new macro PCIE_MSI_ALL_MASK and do the same clearing for MSIs, to ensure that we don't start receiving spurious interrupts.
Use this new mask in advk_pcie_handle_msi();

What about 4.19 and 5.4 for this and patch 2/2? I can't apply this to 4.14 without the newer kernels also having it, right?
thanks,
