From a68809bb8d97f6df3296298e932f07b33e939d00 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 4 Nov 2014 10:55:24 -0700 Subject: [PATCH] staging: comedi: addi_apci_3120: use async->events to report hardware error In apci3120_interrupt_dma(), use the async->events to report the hardware error and allow the core to (*cancel) the command instead of calling the (*cancel) function directly.
