+Based on https://lkml.org/lkml/2020/4/1/1206. In original patch, YYLOC declaration was removed.
+However, using original patch, which removes yylloc declaration on 3.18.14 kernel version results in 'yylloc not declared' error.
+See part of the original description below:
+
+gcc 10 will default to -fno-common, which causes this error at link
+time:
+
+  (.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
+
+This is because both dtc-lexer as well as dtc-parser define the same
+global symbol yyloc. Before with -fcommon those were merged into one
+defintion. The proper solution would be to to mark this as "extern",

+From 8c8187d41b99acd4f2078d0fff6807e0eeb47407 Mon Sep 17 00:00:00 2001
+From: Arnd Bergmann <arnd@arndb.de>
+Date: Thu, 26 Jul 2018 10:13:23 +0200
+Subject: [PATCH] ARM: fix put_user() for gcc-8
+
+Building kernels before linux-4.7 with gcc-8 results in many build failures
+when gcc triggers a check that was meant to catch broken compilers:
+
+/tmp/ccCGMQmS.s:648: Error: .err encountered
+
+According to the discussion in the gcc bugzilla, a local "register
+asm()" variable is still supposed to be the correct way to force an
+inline assembly to use a particular register, but marking it 'const'
+lets the compiler do optimizations that break that, i.e the compiler is
+free to treat the variable as either 'const' or 'register' in that case.
+
+Upstream commit 9f73bd8bb445 ("ARM: uaccess: remove put_user() code
+duplication") fixed this problem in linux-4.8 as part of a larger change,
+but seems a little too big to be backported to 4.4.
+
+Let's take the simplest fix and change only the one broken line in the
+same way as newer kernels.
