[PATCH] cpufreq: acpi-cpufreq: Ignore failure from acpi_cpufreq_early_init_acpi

Browse source 
Ignore the return value of early_init_acpi(), as it can give false error
messages.  If there is something really wrong, then register_driver will
fail cleanly with EINVAL later.

[ background: modprobe acpi-cpufreq on systems not capable of speed-scaling
  started failing with 'invalid argument', where previously it would only
  ever -ENODEV

  I'm not 100% happy with the solution. It'd be better to handle
  failure properly, but this is a low-impact change for 2.6.18
  We can always revisit doing this better in .19   --davej.]
