updated ebuild to 2.5.0-r1 with dodoc adjusted.

I can confirm this issue, and found it was fixed upstream by, and more generally, which adds support for kernel 5.8 and greater as per 

Giving the Kernel version in Toralf's emerge-info is 5.11, this is why it occurs.

The simple fix would to be bump the ebuild to at least 2.2.11, the other fix is to add a check to existing ebuild warning that this version isn't compatible with 5.8 or greater.

The fix I am testing locally is to bump this ebuild to the latest version 2.5.0 but that also requires adjusting the relevant dodoc line for the README as they named the README.RST instead of README.

Attached is the ebuild I am using.
