Subject: [PATCH] staging: comedi - correct parameter gainlkup for DAQCard-6024E
in driver ni_mio_cs.c
From: Martin Homuth-Rosemann <homuth-rosemann@....net>
Correct at least one of the incorrect specs for a national instrument
data acquisition card DAQCard-6024E. This card has only four different
gain settings (+-10V, +-5V, +-0.5V, +-0.05V).
