From 2c9be3eacc39948af2341595322c014833699ac5 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 13 Sep 2013 11:32:59 -0700 Subject: [PATCH] hv: delete vmbus_get_debug_info() It's only used once, only contains 2 function calls, so just make those calls directly, deleting the function, and the now unneeded structure entirely.
