From 27cb98142f42432733ac0a0cb2a35330756d5c19 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Sep 2014 16:16:02 -0700 Subject: [PATCH] staging: comedi: s626: clarify COMEDI_CB_EOA code The end-of-acquisition only applies when the cmd->stop_src == TRIG_COUNT. Refactor the code in s626_handle_eos_interrupt() that detects the end-of- acquisition to clarify this.
