Subject: [PATCH stable-4.14] PCI: aardvark: Fix checking for PIO Non-posted Request
Date: Sun, 26 Sep 2021 16:22:11 +0200 [thread overview]
Message-ID: <20210926142212.1701-1-pali@kernel.org> (raw)
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.
