Subject: [PATCH] hw/intc: fix default registers value in
 exynos4210_combiner_read()

Clang static code analyzer show warning:
hw/intc/exynos4210_combiner.c:231:9: warning: Value stored to 'val' is never read
        val = s->reg_set[offset >> 2];

The default register return value should be return 'val'.
