Takashi Iwai d8cac6207e ALSA: cmipci: Allow disabling MPU port via module option ... Patrick May reported that his sound card with CMI8378 chip causes a crash / reboot when accessing the MIDI port that isn't actually present on the board. Moreover, despite of the documentation, passing mpu_port=0 doesn't disable the MIDI port on this board. It implies that the chip is a newer revision and the MPU401 port is integrated and mapped on the PCI register. For this chip model, the driver enables the MPU port unconditionally, so far. Although fixing the unexpected reboot would be the best solution, it's not so trivial to identify the cause. So, as a plan B, this patch extends the existing mpu_port option usage to allow disabling the port by specifying the value 0, just like we applied for fm_port option in commit 2f24d159d5 ("[ALSA] cmipci - Allow to disable integrated FM port"). As default, the MPU port is still enabled, but user can pass mpu_port=0 to disable it.
