From ac1c86c857368eb727b7ca2c7a48bd6e373fa628 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sun, 9 Dec 2012 21:23:30 -0300 Subject: [PATCH] [media] dvb_usb_v2: change rc polling active/deactive logic Use own flag to mark when rc polling is active/deactive and make decisions, like start/stop polling on suspend/resume, against that.
