Some fe drivers will have to do additional initialization in their fe ops.init interfaces when called during resume. Without the additional initialization, fe and tuner driver resume fails. A new fe exit flag value DVB_FE_DEVICE_RESUME is necessary to detect resume case. This patch adds a new define and changes dvb_frontend_resume() to set it prior to calling fe init and tuner init calls and resets it back to DVB_FE_NO_EXIT once fe and tuner init is done.
