Subject: [ 034/122] USB: Remove unused LPM variable.

From: Greg KH <gregkh@...uxfoundation.org>

3.5-stable review patch.  If anyone has any objections, please let me know.

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

From: Sarah Sharp <sarah.a.sharp@...ux.intel.com>

commit c5c4bdf02e518a281b229ae0891b346919e2d291 upstream.

hub_initiated_lpm_disable_count is not used by any code, so remove it.

This commit should be backported to kernels as old as 3.5, that contain
the commit 8306095fd2c1100e8244c09bf560f97aca5a311d "USB: Disable USB
3.0 LPM in critical sections."
