From 61ef4719ea7cb3c019c5eefb73eb37390cb55db6 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 4 Mar 2014 11:29:39 -0700 Subject: [PATCH] staging: comedi: pcl818: fix PCL818_FI_DATAHI The A/D FIFO uses two registers to get each analog data sample. PCL818_FI_DATALO is the LSB of the data and PCL818_FI_DATAHI is the MSB of the data. The current define for PCL818_FI_DATAHI is incorrect and results in the LSB getting read twice.
