Subject: usb: phy: mxs: suspend to RAM causes NULL pointer dereference

From: Stefan Wahren <[email protected]>

commit 543aa4867d4a2dff5fc11e1b688197ee3bad7f89 upstream.

Triggering suspend to RAM via sysfs on a i.MX28 causes a NULL pointer dereference. This patch avoids the oops in mxs_phy_get_vbus_status() by aborting since there is no syscon available.
