device/testing/linux-asus-zenfone3/gcc10-extern_YYLOC_global_declaration.patch

+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",
