From 786bf7fdaca4c75e7eba6e9aa3a8b5775fd21186 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.
