Subject: [PATCH] bus: fsl-mc: dpio: fix alter FQ state command
Date: Fri, 21 Apr 2017 15:00:18 +0300	[thread overview]
Message-ID: <20170421120018.22232-1-horia.geanta@nxp.com> (raw)

When checking the response verb, the valid bit should be masked out,
since its value flips depending on what Response Register
(RR0 /RR1) it's been read from.

Fixes: 321eecb06bfb ("bus: fsl-mc: dpio: add QBMan portal APIs for DPAA2")
Signed-off-by: Horia Geantă <horia.geanta@nxp.com>
