+Subject: [PATCH] Add missing prototypes to function declarations
+
+With Clang 15+ compiler -Wstrict-prototypes is triggering warnings which
+are turned into errors with -Werror, this fixes the problem by adding
+missing prototypes
+
+Fixes errors like
+| log.c:134:24: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
+| static void syslog_init()
+|                        ^
+|                         void
