From aecbc17285caeae98d5e729d02fdc93ded7a0186 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 27 May 2014 10:30:56 -0700 Subject: [PATCH] staging: comedi: pcmmio: use comedi_cmd pointer Use a local variable to access the comedi_cmd as a pointer instead of getting to from the comedi_subdevice pointer. Remove the unnecessary local variables used for the cmd->chanlist_len.
