From 9a84a7d2e7111aa77a9f35da5e669423d11e0d37 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 22 Oct 2014 15:36:53 -0700 Subject: [PATCH] staging: comedi: comedi_parport: use comedi_buf_write_samples() Use comedi_buf_write_samples() to add the sample to the async buffer. The async events COMEDI_CB_BLOCK and COMEDI_CB_EOS will be detected and set by the core. Remove the unnecessary events in the driver.
