[media] dvb-usb-v2: remove dvb_usb_device NULL check

2014-09-02T18:46:50Z

Reported by Dan Carpenter: The patch d10d1b9ac97b: "[media] dvb_usb_v2: use dev_* logging macros" from Jun 26, 2012, leads to the following Smatch complaint: drivers/media/usb/dvb-usb-v2/dvb_usb_urb.c:31 dvb_usb_v2_generic_io() error: we previously assumed 'd' could be null (see line 29) ... Remove whole check as it must not happen in any case. Driver is totally broken if it does not have valid pointer to device.

[media] dvb_usb_v2: switch interruptible mutex to normal

2012-11-09T14:33:58Z

Fixes error: dvb_usb_v2: pid_filter() failed=-4 error code -4 is EINTR, Interrupted system call That error blocks I/O in some cases as -EINTR error was returned by the mutex which was protecting USB control messages. We want configure hardware to sleep mode on every case after tuning is stopped. That kind of behavior blocks it, leaving hardware some unwanted state in worst case. That error was seen every time when af9015 was plugged to USB1.1 which leads use of hardware PID filters. Stop tuning (tzap) with ctrl+c failed as driver tries to remove hardware PID filters. Tested with every hardware which uses routine in question. Signed-off-by: Antti Palosaari Signed-off-by: Mauro Carvalho Chehab
