------------------------------------------------------
Subject: genirq: msi: make the msi boolean tests return either 0 or 1
From: "Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>
This allows the output of the msi tests to be stored directly in a bit field.
If you don't do this a value greater than one will be truncated and become 0.
Changing true to false with bizare consequences.
