Jassi, I missed this note and merged the following patches, introducing the forecasted issue in linux-next. To remedy this, I took the liberty of merging this patch as well into the remoteproc tree.

No problem.

The qcom,intents property is a list of pairs, thus it should be defined as uint32-matrix.
