Subject: [PATCH] ACPI: scan: Ignore MAGN0001
Date: Fri, 21 Apr 2023 18:27:02 +0200 [thread overview]
Message-ID: <20230421162702.3558-1-mail@mariushoch.de> (raw)
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.
