[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicholas Mc Guire <hofrat@xxxxxxxxx>

[ Upstream commit 342639d996f18bc0a4db2f42a84230c0a966dc94 ]

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.

Fixes: ab597d35ef11 ("PCI: xilinx-nwl: Add support for Xilinx NWL PCIe Host Controller")
