Subject: acpi: fan after suspend-to-mem fix
From: Tommi Kyntola <[EMAIL PROTECTED]>
acpi_fan_suspend should probably set state to ACPI_D3, rather than ACPI_D0.
With this change the fan works after S3 suspend atleast on HP nw8000
laptop, for which the suspended fan has been broken since sword-and-stone.
Why this was ACPI_D0 beats me, but it's been that way since the
_suspend/_resume functios got added in the commit
0feabb01d93e5801d1127416a66cfc3963280bca (2.6.18-rc1, I think).
The fan hasn't worked on my HP nw8000 laptop after an S3 suspend ever, but
fixing that to ACPI_D3 there finally makes it work as expected.
If there was some hidden reason why that was set to ACPI_D0, then perhaps a
config option for some ICH4 or HP laptops is called for.
