Bug Description
When CONFIG_GOLDFISH_BUS is set to "y", the goldfish_pdev_bus driver is compiled into the kernel and claims the serial UART, breaking serial communications with the following kernel message: "genirq: Flags mismatch irq 4. 00000000 (serial) vs. 00000080 (goldfish_
I checked the configs for 4.4 in Yakkety and Xenial and 4.5 in mainline and found that CONFIG_GOLDFISH was set to "n" there, completely disabling all the goldfish drivers. Since this is a driver for the Android emulator, I'm not even sure it is appropriate to be enabled at all for desktop systems, but the goldfish_pdev_bus driver breaking serial definitely shouldn't happen.
