Subject: staging: comedi: adl_pci9118: ai (*insn_read) does not use interrupts
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bdbeaed3f869d474774edc72a8f1ba6e091e2d82;p=deliverable%2Flinux.git

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.
