[Qemu-devel] [PATCH v2 1/2] spapr_pci: convert g_malloc() to g_new()

[Greg Kurz]

When allocating an array, it is a recommended coding practice to call
g_new(FooType, n) instead of g_malloc(n * sizeof(FooType)) because
it takes care to avoid overflow when calculating the size of the
allocated block and it returns FooType *, which allows the compiler
to perform type checking.
