ACPI: silence kmemcheck false positive
This addresses: https://bugzilla.kernel.org/show_bug.cgi?id=14998
We copy some strings into "event" but we leave the space after the NULL
terminators uninitialized. Later in acpi_bus_receive_event() we copy
the whole struct to another buffer with memcpy(). If the new buffer is
stored on the stack, kmemcheck prints a warning about the unitialized
space after the NULL terminators.
It's true that the space is uninitialized, but it's harmless. The
buffer is only used in acpi_system_read_event() and we don't read past
the NULL terminators.
This patch changes the kmalloc() to kzalloc() so that we initialize the
memory and silence the kmemcheck warning.
