[Qemu-trivial] [PATCH 18/29] hw/m68k/mcf5206.c: Fix memory leak spotted by valgrind

[Shannon Zhao]

From: Shannon Zhao <address@hidden>

valgrind complains about:
==16659== 1,912 (112 direct, 1,800 indirect) bytes in 1 blocks are definitely 
lost in loss record 1,254 of 1,285
==16659==    at 0x4C2845D: malloc (in 
/usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)
==16659==    by 0x251F97: malloc_and_trace (vl.c:2556)
==16659==    by 0x64C770E: g_malloc (in /usr/lib64/libglib-2.0.so.0.3600.3)
==16659==    by 0x2C994F: qemu_extend_irqs (irq.c:55)
==16659==    by 0x2C99DB: qemu_allocate_irqs (irq.c:64)
==16659==    by 0x225878: mcf5206_init (mcf5206.c:539)
==16659==    by 0x223991: an5206_init (an5206.c:61)
==16659==    by 0x256362: main (vl.c:4249)
