From fbd7af041586a15f5dc15b9ec051d25aa5ebe00a Mon Sep 17 00:00:00 2001 From: Wen Yang Date: Tue, 5 Mar 2019 19:32:56 +0800 Subject: [PATCH] ARM: rockchip: add missing of_node_put in rockchip_smp_prepare_pmu The call to of_get_next_child returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: ./arch/arm/mach-rockchip/platsmp.c:250:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 241, but without a corresponding object release within this function. ./arch/arm/mach-rockchip/platsmp.c:260:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 241, but without a corresponding object release within this function. ./arch/arm/mach-rockchip/platsmp.c:263:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 241, but without a corresponding object release within this function.
