------------------------------------------------------
Subject: cpufreq: acpi-cpufreq: Ignore failure from acpi_cpufreq_early_init_acpi
From: Dave Jones <davej@xxxxxxxxxx>
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.]
