From 8e7fed7ed760275c3e8e73e4328751fcb8f21642 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Sep 2014 16:15:58 -0700 Subject: [PATCH] staging: comedi: pcmuio: 'stop_count' is always 'stop_arg' When the cmd->stop_src == TRIG_COUNT, the 'stop_count' is the cmd->stop_arg. For any other stop_src the 'stop_count' is 0, which is also the cmd->stop_arg. Simplify the 'stop_count' initialization.
