+Subject: [PATCH] scripts/dtc: Remove redundant YYLOC global declaration
+
+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",
+however that leads to:
+
+ dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]
+ 26 | extern YYLTYPE yylloc;
+ | ^~~~~~
+In file included from dtc-lexer.l:24:
+dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here
+ 127 | extern YYLTYPE yylloc;
+ | ^~~~~~
+cc1: all warnings being treated as errors
+
+which means the declaration is completely redundant and can just be
+dropped.
