Subject[PATCH] ohci-nxp: Use ohci_finish_controller_resume()
Date
OHCI drivers are supposed to use ohci_finish_controller_resume(). This patch
adds respective suspend and resume code to ohci-nxp. The following compiler
warning is fixed this way:

drivers/usb/host/ohci-hub.c:321: warning: 'ohci_finish_controller_resume'
defined but not used
