From 1f2706828d7e534a9751bcc63f9a5797fdc38284 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 23 Apr 2014 16:06:54 -0700 Subject: [PATCH] staging: comedi: adv_pci1710: remove 'ai_chanlist' from private data This member of the private data is just a copy of the cmd->chanlist. Use that instead.
