From 3a14580411adfb75f9a44eded9f41245b9e44606 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Mon, 21 Mar 2022 01:16:48 +0000 Subject: kernel: delete Linux 5.4 config and patches As the upcoming release will be based on Linux 5.10 only, remove all kernel configuration as well as patches for Linux 5.4. There were no targets still actively using Linux 5.4.
