From 1f44c034de2e1591f4fad38c685dd167e1da7062 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 22 Oct 2014 15:37:00 -0700 Subject: [PATCH] staging: comedi: pcl711: use comedi_buf_write_samples() Use comedi_buf_write_samples() to add the sample to the async buffer. The async events will set properly by the core. Remove the unnecessary events in the driver.
