From ec4a162af388a2716c5314c4aff7029071d09f57 Mon Sep 17 00:00:00 2001 From: James Morris Date: Fri, 7 May 2010 09:19:29 +1000 Subject: Revert "TPM: ACPI/PNP dependency removal" This reverts commit b89e66e1e396f7b5436af154e58209320cc08aed. > > When CONFIG_PM is not set: > > > > drivers/built-in.o: In function `acpi_init': > > bus.c:(.init.text+0x2d84): undefined reference to `pm_flags' > > bus.c:(.init.text+0x2d91): undefined reference to `pm_flags' > > CONFIG_ACPI depends on CONFIG_PM, > so acpi/bus.c should not be compiled for CONFIG_PM=n > > Hmm, is is somebody doing something strange, like "select ACPI" > without guaranteeing that all of ACPI's dependencies are satisfied?
