This marks 0x29 as accelerometer address on Dell Precision 3551.
I followed previous works of Paul Menzel and Hans de Goede to verify it:
$ cd /sys/bus/pci/drivers/i801_smbus/0000\:00\:1f.4
$ ls -d i2c-?
i2c-0
$ sudo modprobe i2c-dev
$ sudo i2cdetect 0
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0.
I will probe address range 0x08-0x77.
Continue? [Y/n] Y

Kind regards,

PS: Just a heads-up, that you have a DMARC policy set:
$ dig txt _dmarc.aiyionpri.me +short
"v=DMARC1;p=reject;"
I believe STRATO enabled this for all their customers, breaking
deliveries for addressees enforcing the DMARC policy, as you do not have
any SPF entries for example [1]. I recommend to deactivate the setting
by selecting *Keine STRATO-DMARC-Regel* [2], and to look for another
provider, as their support was not helpful at all and did not even
understand the problem, and hasn’t replied to my latest response in
several weeks. (And I didn’t get the initial emails informing about the
change.)

Thank you for your contribution, it has been applied to my local
review-ilpo-fixes branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-fixes branch only once I've pushed my
local branch there, which might take a while.
