Subject: [PATCH 07/11] vga_switcheroo: Reprobe old device on switching
Date: Sun,  1 Jun 2014 12:38:39 -0400	[thread overview]
Message-ID: <1401640723-2058-8-git-send-email-matthew.garrett@nebula.com> (raw)
In-Reply-To: <1401640723-2058-1-git-send-email-matthew.garrett@nebula.com>

We need to force the previously active device to reprobe its connectors
when we switch in order to allow it to give up connectors that are no
longer in use.
