Subject: [PATCH] Correct DSDT Address field in FACP tables
9897bb
9897bb
The FADT allows either the DSDT Address or XDSDT Address field to be
9897bb
zero.  However, the table definition used by the table compiler still
9897bb
requires the DSDT Address to be non-zero, which is not correct.  So,
9897bb
remove the DT_NON_ZERO flag from the field.
