Missing Windows drivers after updating display drivers

Today I updated the device drivers for the AMD Radeon R7 M265 graphics card in my Lenovo ideapad 320-15abr laptop. Per the instructions on the AMD Driver and Support website I uninstalled the previous version before install the latest version.  After the display drivers successfully installed I noticed that I am now missing drivers for the following two items.

- PCI Encryption/Decryption Controller

- SM Bus Controller

Are these devices controlled by AMD drivers?  If so how to I install these drivers? My laptop has an AMD processor if that matters any.

Thank you!

1. what laptop do you have?
2. why not install the chipset-drivers aswell?

PC: R7 2700X @PBO + RX 580 4G (1500MHz/2000MHz CL16) + 32G DDR4-3200CL14 + 144hz 1ms FS P + 75hz 1ms FS
Laptop: R5 2500U @30W + RX 560X (1400MHz/1500MHz) + 16G DDR4-2400CL16 + 120Hz 3ms FS

Thank you for your reply!  The laptop I have is a Lenovo ideapad 320-15abr.  I wasn't aware I needed to install the chipset drivers as well.  Looking back at the AMD Radeon Drivers and Support page I can see there is a section to download Chipset drivers.  How do I know which chipset I need to download?  I can see on the Lenovo website they have a chipset driver to download, but it's from 2017.

i would recommend installing the chipset-driver from Lenovo, as they may have altered it in some way with OEM-profiles ;)

if this doesnt work for you i will check what amd.com/support offers you as driver ;)

I Installed the chipset drivers from the Lenovo website and the device manager still says I'm missing drivers for the same two devices.  Would there be any harm in downloading the AMD Auto-Detect and Install tool and using that to install / update any drivers I need?  Would that include the drivers I'm missing?  Thank you for all your help.
