media: i2c: tvp5150: Add of_node_put() before goto
Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a goto from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the goto in four places. Issue found with Coccinelle.
