If anyone has any objections, please let me know. ------------------ From: Dan Carpenter 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.
