From 404aaed16b31ea34efc5fc58c7b0ba71d7f09077 Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Fri, 29 Apr 2011 13:45:00 -0700 Subject: [PATCH] Staging: hv: Get rid of vmbus_release_unattached_channels() as it is not used Since vmbus_release_unattached_channels() is only used in module unload path and since the vmbus driver cannot be unloaded, get rid of this "dead" code.
