Subject: [PATCH] PCI: xilinx-nwl: add missing of_node_put()
Date: Thu, 14 Jun 2018 11:04:34 +0200 [thread overview]
Message-ID: <1528967074-30024-1-git-send-email-hofrat@osadl.org> (raw)
The call to of_get_next_child() returns a node pointer with
refcount incremented thus it must be explicitly decremented
here after the last usage.
Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org>
Fixes: commit ab597d35ef11 ("PCI: xilinx-nwl: Add support for Xilinx NWL PCIe Host Controller")
---
Problem found by an experimental cocinelle script
Patch was compile tested with: multi_v7_defconfig + ARCH_ZYNQ=y,
COMPILE_TEST=y, PCIE_XILINX_NWL=y
(one sparse warning though not related to the change proposed though)
Patch is against 4.17.0 (localversion-next is next-20180613)
