Dmesg: ACPI BIOS Error (bug): Could not resolve symbol [^^RP28.PXSX.WIST]

Framework Laptop 12 Linux

I am a Framework Laptop 12 Batch 1, gray color user. I am seeing the following errors related to the ACPI, BIOS, and USB-C. Is that a problem? How to suppress the errors?

$ cat /etc/fedora-release
Fedora release 42 (Adams)

$ uname -r
6.15.5-200.fc42.x86_64

My BIOS info is below. I picked up the command from this page.

$ sudo dmidecode | grep -A3 'Vendor:\|Product:' && sudo lshw -C cpu | grep -A3 'product:\|vendor:'
