DSDT Override: Is this correct?

DSDT Override: Is this correct?

[Nigel Cunningham]

Hi.

I'm just trying to override the DSDT using the 2.4.21-pre3 kernel, and
had to stick a struct in front of the (acpi_table_header *) cast. Can I
get confirmation that this the the right thing to do?

Regards,

Nigel

In the meantime, yes.
