net-misc/dahdi-2.10.1 fails to compile on a system with sys-kernel/gentoo-sources-4.0.0. Upstream has solved the issue with two commits (1cc0ad510acd404e63923ed3062b9302d53580da and 1559db9d1ae03780788788c07334ca54cdd1253a).

I can confirm that the patches applies and compiles fine (with kernel 3.19.3 in my case). No further tests done which follows 'til tomorrow.
Created attachment 402588 [details, diff] Patches for kernel 4.x from upstream
Using the patched dahdi in production system and did some calls via dahdi/wcb4xxp. Everything is normal by now.
+*dahdi-2.10.1-r1 (14 May 2015) + + 14 May 2015; Tony Vroon <chainsaw@gentoo.org> +dahdi-2.10.1-r1.ebuild: + Two upstream patches as scavenged by Erich Seifert & Oliver Jaksch restore + compatibility with kernel 4.0 and higher. Closes bug #546530. My apologies for the severe delay gentlemen.
