From a192a9580bcc41692be1f36b77c3b681827f566a Mon Sep 17 00:00:00 2001 From: Len Brown Date: Tue, 28 Jul 2009 16:45:54 -0400 Subject: ACPI: Move definition of PREFIX from acpi_bus.h to internal..h Linux/ACPI core files using internal.h all PREFIX "ACPI: ", however, not all ACPI drivers use/want it -- and they should not have to #undef PREFIX to define their own. Add GPL commment to internal.h while we are there. This does not change any actual console output, asside from a whitespace fix.

Same story for acpi_table_parse(), which is a top-level API to Linux/ACPI. This is necessary for building some code that used to always depend on CONFIG_ACPI=y, but will soon also need to build with CONFIG_ACPI=n.
