Re: [PATCH] [BUILD_FAILURE] 2.6.25-rc2-mm1 - Build Failure at acpi_os

[Len Brown <lenb@kernel.org>]

works for me!

applied.

thanks,
-len

ps.  CONFIG_ACPI_CUSTOM_DSDT's only use is to guard the use of
CONFIG_ACPI_CUSTOM_DSDT_FILE:

#ifdef CONFIG_ACPI_CUSTOM_DSDT
#include CONFIG_ACPI_CUSTOM_DSDT_FILE
#endif

we could get rid of it if cpp could so something like

#if (CONFIG_ACPI_CUSTOM_DSDT_FILE != "")
#include CONFIG_ACPI_CUSTOM_DSDT_FILE
#endif

but it doesn't look like cpp has a concept of strings in expressions.
