From 30fa96a34694d93bf76311944c9521bbcdd4e58e Mon Sep 17 00:00:00 2001 From: Matt Schulte Date: Wed, 21 Nov 2012 09:40:49 -0600 Subject: [PATCH] tty/8250 Add XR17D15x devices to the exar_handle_irq override Add XR17D15x devices to the exar_handle_irq override: they have the same extra interrupt register that could fire and never be serviced by the standard handle_irq.
