From 9b7935f72f9be674d2177c395f3cfb62283dc97e Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 6 Dec 2019 16:26:00 +0100 Subject: [PATCH] lib: raid6: fix awk build warnings commit 702600eef73033ddd4eafcefcbb6560f3e3a90f7 upstream. Newer versions of awk spit out these fun warnings: awk: ../lib/raid6/unroll.awk:16: warning: regexp escape sequence `\#' is not a known regexp operator As commit 700c1018b86d ("x86/insn: Fix awk regexp warnings") showed, it turns out that there are a number of awk strings that do not need to be escaped and newer versions of awk now warn about this. Fix the string up so that no warning is produced. The exact same kernel module gets created before and after this patch, showing that it wasn't needed.
