Subject[PATCH] bus: fsl-mc: dpio: fix alter FQ state command
Date
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")
