From 8b9505527e5560297be00094fb4819b0e91e4138 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Sep 2014 16:16:03 -0700 Subject: [PATCH] staging: comedi: s626: 'ai_sample_count' is always 'stop_arg' When the cmd->stop_src == TRIG_COUNT, the 'ai_sample_count' is the cmd->stop_arg. For a stop_src == TRIG_NONE the 'ai_sample_count' is currently set to 1 but the driver never actually uses the value. Simplify the 'stop_count' initialization by just setting it to the cmd->stop_arg.
