From dc917419212f80fa90ecbfa7bce10aa98183db45 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 4 Mar 2014 11:29:57 -0700 Subject: [PATCH] staging: comedi: pcl816: move pcl816_reset() For aesthetics, move this function to follow the pcl812 and pcl818 drivers better. Remove the commented out cut-and-paste code from the pcl818 driver.
