 Description:
 		The /sys/devices/.../msi_irqs directory contains a variable set
-		of sub-directories, with each sub-directory being named after a
-		corresponding msi irq vector allocated to that device.  Each
-		numbered sub-directory N contains attributes of that irq.
-		Note that this directory is not created for device drivers which
-		do not support msi irqs
+		of files, with each file being named after a corresponding msi
+		irq vector allocated to that device.
