Subject: [PATCH] PCI: fix potential resource leak in drivers/pci/msi.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f01f4182597a3bb4b6fbf92e041faf7a1016f4b6;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] PCI: fix potential resource leak in drivers/pci/msi.c

The coverity checker spotted (as entry #599) that we might leak `entry' in
drivers/pci/msi.c::msix_capability_init()
This patch should take care of that.
