Subject: [PATCH 0/2] dmaengine: mv_xor: fix child node handling and switch
 to scoped loop

This series fixes a wrong handling of the child node within the
for_each_child_of_node() by adding the missing calls to of_node_put() to
make it compatible with stable kernels that don't provide the scoped
variant of the macro, which is more secure and was introduced early this
year. The switch to the scoped macro is the next patch, which makes the
coe more robust and will avoid such issues in new error paths.
