From 5790a1589f746d5648825d3bc8367f0ce7b12784 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 4 Mar 2016 17:20:12 -0300 Subject: [media] exynos4-is: Put node before s5pcsis_parse_dt() return error The MIPI CSIS DT parse function return an -ENXIO errno if the port # is outside of the supported values. But it doesn't call of_node_put() to decrement the node's reference counter, that's incremented inside the of_graph_get_next_endpoint() function that was called before. Instead of just returning, go to the error path that already does it.
