In your text, it should be "not" and not "don't".

I could suggest also:

patchdir '%s' not found

Or explicit in the message that "Patch source directory" not found means "patchdir" is incorrect somewhere in SRC_URI.

I think you could even tell which patch file has its patchdir incorrect by printing the "local" variable. Not sure it brings anything, just thinking out loud 😁

Anyway, I like this patch, but it does not have the same purpose as the earlier version of this patch series. I think it is also important to print the patchdir when the patch tool fails to apply the patch. It might be because the path exists but is incorrect.

So it'd be awesome if we can get the patchdir in the fatal message when the patch fails to apply. My understanding of patch.bbclass and lib/oe/patch.py is that resolver.Resolve() is doing the patching so in that except thr patchdir could be printed.

Many thanks!
Quentin
