Subject: [PATCH] i2c: fix device_node_continue.cocci warnings

 Device node iterators put the previous value of the index variable, so an
 explicit put causes a double put.

Generated by: scripts/coccinelle/iterators/device_node_continue.cocci

Please take the patch only if it's a positive warning. Thanks!

I haven't checked anything more that what is shown in the patch.
