    Subject[PATCH 5.13 243/266] PCI: aardvark: Fix checking for PIO Non-posted Request
    Date
    From: Pali Rohár <pali@kernel.org>

    commit 8ceeac307a79f68c0d0c72d6e48b82fa424204ec upstream.

    PIO_NON_POSTED_REQ for PIO_STAT register is incorrectly defined. Bit 10 in
    register PIO_STAT indicates the response is to a non-posted request.
