From b20d6f793c5bd0493b26d04cbc7ce04c1c5cea0e Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 5 Oct 2015 15:47:25 -0700 Subject: [PATCH] staging: comedi: pcl812: convert hardware type defines into an enum For aesthetics, convert these defines into an enum and rename the CamelCase. Fix the switch() code to use the enum without warnings.
