From bdbeaed3f869d474774edc72a8f1ba6e091e2d82 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 5 Sep 2014 09:25:41 -0700 Subject: [PATCH] staging: comedi: adl_pci9118: ai (*insn_read) does not use interrupts The analog input (*insn_read) in this driver is done as a software-triggered, polled operation. The PCI9118_AI_CTRL_INT bit in the control register, which is actually set in setup_channel_list(), should not be set.
