2.6.10 and acpi_get_possible_resources?

2.6.10 and acpi_get_possible_resources?

[Jurgen Kramer]

I am trying to get the WACOM ACPI patches working on 2.6.10 but it bails
out on a missing function "acpi_get_possible_resources". On 2.6.9 the
needed symbol is exported by acpi_ksyms.c but this file no longer exists
in 2.6.10. 

What is the best way to get the acpi_get_possible_resources function
exported properly? It is defined in <acpi/acpxf.h> but adding this to
the wacom source files did not help.

The 2.6.9 version of the wacom patches are from:

http://www.theory.bham.ac.uk/staff/schofield/linux/tc1100/linux-2.6.9-
wacom_acpi.patch


Thanks,

Jurgen

Problem solved. The functions from <acpi/acpixf.h> needed a #define
ACPI_FUTURE_USAGE 1 to work again.

My wacom tablet is working again with 2.6.10.

A better fix, though, would be to move the specific export you
need out of the FUTURE_USAGE define. This ifdef was introduced
to eliminate bloat due to unused exports, and including it all
back in defeats the purpose.

You are right of course but it only applies if the patches were to be
included in the mainline ACPI tree. For now it's just me using the
"acpi_get_possible_resources" function here at home.
