Subject: Accelerometer lis3lv02d is present on SMBus but its address is unknown, skipping registration
Date: Mon, 27 Feb 2023 15:23:13 +0100 [thread overview]
Message-ID: <97708c11-ac85-fb62-2c8e-d37739ca826f@molgen.mpg.de> (raw)
Dear Linux folks,
On the Dell Precision 3540, BIOS 1.23.0 12/19/2022, with Debian
sid/unstable, Linux 6.1.12 logs the warning below:
Accelerometer lis3lv02d is present on SMBus but its address is
unknown, skipping registration
This warning was already logged by
Linux version 5.19.0-2-amd64 (debian-kernel@lists.debian.org)
(gcc-11 (Debian 11.3.0-6) 11.3.0, GNU ld (GNU Binutils for Debian)
2.38.90.20220713) #1 SMP PREEMPT_DYNAMIC Debian 5.19.11-1 (2022-09-24)
with firmware BIOS 1.15.0 12/08/2021.
What can a user do about this? It looks like the I2C addresses need to
be added to `dell_lis3lv02d_devices[]` in `drivers/i2c/busses/i2c-i801.c`.
Kind regards,
Paul
