Add 0x29 as the accelerometer address for the Dell Latitude 5500 to
lis3lv02d_devices[].
The address was verified as below:
$ cd /sys/bus/pci/drivers/i801_smbus/0000:00:1f.4
$ ls -d i2c-?
i2c-2
$ sudo modprobe i2c-dev
$ sudo i2cdetect 2
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-2.
I will probe address range 0x08-0x77.
Continue? [Y/n] Y

Thanks, patch looks good to me:
Reviewed-by: Hans de Goede <hansg@kernel.org>
Note with kernels >= 6.14 you could have also used the new
probe_i2c_addr module option for the dell-lis3lv02d module.
Regards,
Hans

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.
