Subject: staging: fsl-mc/dpio: Propagate error code
Git-commit: 30c9dbf3174e75e8c721aa2c7d47bf8fcd40d8cb
Patch-mainline: v4.13-rc1
References: fate#326530,fate#326531,fate#326535,fate#326538,fate#326539
dpaa2_io_service_register() returns zero even if
qbman_swp_CDAN_set() encountered an error. Fix this
by propagating the error code so the caller is informed
data availability notifications are not properly set
for a channel.
