[ 167/262] xhci: Fix a logical vs bitwise AND bug

[Greg Kroah-Hartman]

From: Greg KH <gregkh@xxxxxxxxxxxxxxxxxxx>

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

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

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 052c7f9ffb0e95843e75448d02664459253f9ff8 upstream.

The intent was to test whether the flag was set.

This patch should be backported to stable kernels as old as 3.0, since
it fixes a bug in commit e95829f474f0db3a4d940cae1423783edd966027 "xhci:
Switch PPT ports to EHCI on shutdown.", which was marked for stable.
