Potential fix for the issue described in #563 by ignoring "write error: Device or resource busy" error message when writing a value.

Thank you for the PR, since these changes seem strictly AMD oriented, I've asked on auto-cpufreq discord channel if someone could test these changes.

Tried on my laptop with a Ryzen 7 and looks like it's not apearing anymore on journalctl but I have the same problem where on auto-cpufreq it shows that it can set EPP because it not supported

@Tresillo2017 this issue was fixed with #631 can you make sure you have pulled the latest changes on master branch?

I'm not sure this is related to #631 since that was a fix for Intel CPUs.

You're using the acpi-cpufreq driver which does not support EPP, so this is not a bug. If you would like EPP support, you'll need to switch to using amd-pstate-epp

And how can I do that? By not typing anything into the grub parameters?

That was a really quick reply, thx for that. And now it's working as supposed, let's se if my battery life improves I was getting 3-4h of battery life out of the box on a thinkpad e16 amd.
