sbshc: acpi_device_class "smbus_host_controller" too long
acpi_device_class can only be 19 characters and a NULL terminator. With the current name we get a buffer overflow in acpi_smbus_hc_add() when we do: strcpy(acpi_device_class(device), ACPI_SMB_HC_CLASS); Signed-off-by: Dan Carpenter <error27@gmail.com> Cc: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com>
