Subject: [media] media: em28xx-dvb update fe exit flag to indicate device disconnect Author: Shuah Khan <[email protected]> Date: Sat Jul 12 13:44:13 2014 -0300 Change em28xx_dvb_fini() to set fe exit flag to DVB_FE_DEVICE_REMOVED when device is disconnected. em28xx maintains device disconnect status in em28xx device. fe drivers will be able to now check the fe exit status to avoid accessing the device, from their release interfaces when called from disconnect path. This change depends on dvb-core change that exports fe exit flag by moving it from fepriv to fe.
