From 278512665094888d3c007fdd74e090496d6c811d Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Fri, 9 Oct 2020 21:53:35 +0200 Subject: kernel: remove support for kernel 4.19 We use 5.4 on all targets by default, and 4.19 has never been released in a stable version. There is no reason to keep it.
