[PATCH] cpufreq: acpi-cpufreq: Ignore failure from acpi_cpufreq_early_init_acpi
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.] Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Dave Jones <davej@redhat.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
