Title:
modules for non-existent hardware are loaded for unknown reason
(Ubunntu 20.04, kernel 5.4.0-80-generic)
Status in initramfs-tools package in Ubuntu:

Status in linux package in Ubuntu:
Incomplete
Bug description:
My laptop is Asus X302LA. I removed its HDD and plugged it externally via
USB-SATA convertor.
To restore the system's bootability, I had to switch from MODULES=dep to
MODULES=most in /etc/initramfs-tools/initramfs.conf and regenerate initramfs
images by command
update-initramfs -u -k all
After a successful boot I checked lsmod output and was surprised by a number
of loaded modules for seemingly absent hardware. Like, inv_mpu6050 and ak8975.
Do I have a way to check this hardware is actually present and is reporting
any meaningful data ?
If no, do Ubuntu maintainers of linux kernel and initramfs tools have a way
to avoid loading these modules when their hardware is absent ?
