From 04a7279ff12fc47b657f70731d401c0064f5838a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 19 Dec 2017 09:26:17 +0100 Subject: [PATCH] cfg80211: ship certificates as hex files Not only does this remove the need for the hexdump code in most normal kernel builds (still there for the extra directory), but it also removes the need to ship binary files, which apparently is somewhat problematic, as Randy reported. While at it, also add the generated files to clean-files.
