staging: fsl-mc/dpio: Fix early writing of valid bit
Commands written to the QMan software portals have a valid bit in the "verb" field of the command that, when set with the right value, notifies the hardware that the command is fully written and ready to be processed. The "verb" field should be the last one to be written in the swp command registers, after all other fields are filled in. The current implementation doesn't follow this rule for all commands, which may result in an incompletely configured command being processed by the hardware. Enforce the correct order of writes to avoid this situation. Signed-off-by: Ioana Radulescu <ruxandra.radulescu@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
