Subject[PATCH] ACPI: scan: Ignore MAGN0001
Date
The LSM303D on the Lenovo Yoga Tablet 2 series is present
as both ACCL0001 and MAGN0001. As we can only ever register an
i2c client for one of them, ignore MAGN0001.

Currently this errors:
i2c i2c-4: Failed to register i2c client MAGN0001:00 at 0x1d (-16)

Tested on a Lenovo Yoga Tablet 2 1051-F.
