From 71ba7506f05e6512e4b25df2233fa238025399d5 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 27 May 2014 10:30:47 -0700 Subject: [PATCH] staging: comedi: amplc_dio200_common: use comedi_cmd pointer Use the local variable to access the comedi_cmd as a pointer in dio200_read_scan_intr() instead of getting to it from the comedi_subdevice pointer. Remove the unnecessary local variable 'len', this is just the cmd->chanlist_len.
