From: H Hartley Sweeten Date: Thu, 18 Sep 2014 18:35:34 +0000 (-0700) Subject: staging: comedi: comedi_test: use comedi_handle_events() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2405124744245aff25e72c625456f609bca8ccd2;p=linux-beck.git staging: comedi: comedi_test: use comedi_handle_events() Use comedi_handle_events() to automatically (*cancel) the async command for an end-of-acquisition or if an error/overflow occurs. For aesthetics, add a local variable for the comedi_subdevice pointer.
