From b0d56f2f4f1f4f7ecdf96f0a0246d0db5392e075 Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Thu, 28 Jul 2016 14:39:21 +0100 Subject: [PATCH] anv: remove internal 'validate' layer Presently the layer has only a single entry point. As mentioned by Jason the function does not validate anything that isn't checked elsewhere, thus we can drop the whole thing.
