Subject: rtl818x_pci: Disable pci device in error handling code
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1c76b4902c26c73283bb3578829dd0cfe53ce10a;p=deliverable%2Flinux.git

rtl818x_pci: Disable pci device in error handling code

When pci_request_regions in rtl8180_probe fails, pci_disable_device is not
called to disable the device which is enabled by pci_enbale_device.

This patch fixes the problem by adding a new lable in error handling code.
