From dd159eeca971d594fa30176733b66d37acda82a3 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 4 Oct 2006 02:16:32 -0700 Subject: [PATCH] genirq: msi: make the msi boolean tests return either 0 or 1 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. Signed-off-by: Eric W.
