From bf8d0e947fd885e62daa66cfb14fd85dc97e73af Mon Sep 17 00:00:00 2001 From: David Binder Date: Fri, 17 Mar 2017 11:27:03 -0400 Subject: [PATCH] staging: unisys: visorbus: Remove useless checks in visorbus_main.c Removes checks that all visor_device instances have an associated visorchannel. Due to the design of the s-Par drivers these checks are unnecessary.
