From 512bd18da5a0eab33f48b56327fb7812bb05e886 Mon Sep 17 00:00:00 2001 From: Alan Somers Date: Wed, 22 Nov 2017 19:58:29 +0000 Subject: [PATCH] Add a test case for cam_get_device with sa(4) devices sa(4) has some unique behavior that is special-cased in cam_get_device. The existing tests don't provide coverage for this special case.
