[Qemu-devel] [PATCH v2 02/13] hw/isa/lpc_ich9.c: Fix misusing qemu_allocate_irqs for single irq

[Shannon Zhao <zhaoshenglong@huawei.com>]

From: Shannon Zhao <shannon.zhao@linaro.org>

valgrind complains about:
==25058== 8 bytes in 1 blocks are definitely lost in loss record 623 of 3,473
==25058==    at 0x4C2845D: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)
==25058==    by 0x2EB657: malloc_and_trace (vl.c:2556)
==25058==    by 0x64C770E: g_malloc (in /usr/lib64/libglib-2.0.so.0.3600.3)
==25058==    by 0x377C27: qemu_extend_irqs (irq.c:55)
==25058==    by 0x377CB3: qemu_allocate_irqs (irq.c:64)
==25058==    by 0x222338: ich9_lpc_pm_init (lpc_ich9.c:365)
==25058==    by 0x255C42: pc_q35_init (pc_q35.c:255)
==25058==    by 0x2EFA22: main (vl.c:4249)

Since ich9_lpc_pm_init only requests one irq, so let it just call
qemu_allocate_irq.
