Subject[PATCH 4.4 110/193] Drivers: hv: vmbus: fix build warning
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sudip Mukherjee <sudipm.mukherjee@gmail.com>

commit 9220e39b5c900c67ddcb517d52fe52d90fb5e3c8 upstream.

We were getting build warning about unused variable "tsc_msr" and
"va_tsc" while building for i386 allmodconfig.
