[PATCH] staging: fsl-mc/dpio: Propagate error code

From: Ioana Radulescu
Date: Thu Jun 15 2017 - 04:55:21 EST


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.
