Subject: [PATCH] regulator: of: Add a missing 'of_node_put()' in an error handling path of 'of_regulator_match()'
Git-commit: 30966861a7a2051457be8c49466887d78cc47e97
Patch-mainline: v4.17-rc1
References: bsc#1051510

If an unlikely failure in 'of_get_regulator_init_data()' occurs, we must
release the reference on the current 'child' node before returning.
