Subject: [PATCH 4.19 307/421] PCI: aardvark: Fix checking for PIO Non-posted Request

From: Pali Rohár <pali@...nel.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.
