From 90476670abec373557a6bff6a43b6e490c02e4ec Mon Sep 17 00:00:00 2001 From: Sameer Wadgaonkar Date: Wed, 27 Sep 2017 13:14:44 -0400 Subject: staging: unisys: visorbus: simplify visorchannel_create_guts Removing the two wrapper functions dealing with visorchannel_create() and instead just always use a new version of visorchannel_create() with an additional parameter.
