3.16.7-ckt3 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Mark Rustad <[email protected]> commit 508a8c9e264e1057f663e578c47c5ffa00adb160 upstream. In ixgbe_probe, the code at label err_dma can dereference adapter when it has a NULL value. The check is there to avoid disabling a disabled device. When adapter is NULL, treat it as if the device is enabled, because it is enabled in that case.
