In 'dib0700_i2c_xfer_new()' and 'dib0700_i2c_xfer_legacy()' we are taking two locks: 1. i2c_mutex 2. usb_mutex If attempt to take 'usb_mutex' lock fails then the previously taken lock 'i2c_mutex' should be unlocked and -EINTR should be returned so that caller can take appropriate action. If locking attempt was interrupted by a signal then we should return -EINTR. At present we are returning '0' for such scenarios which is wrong. Replace -EAGAIN by -EINTR as a return type for the the scenario where locking attempt was interrupted by signal.

2012-05-15[media] cxd2820r: tweak search algorithm behaviorGianluca Gennari
MPIS based STBs running 3.x kernels and the Enigma2 OS are not able to tune DVB-T channels with the PCTV 290e using the current cxd2820r driver. DVB-T2 channels instead work properly. This patch fixes the problem by changing the condition to break out from the wait lock loop in the "search" function of the cxd2820r demodulator from FE_HAS_SIGNAL to FE_HAS_LOCK. As a consequence, the "search" function of the demodulator driver now returns DVBFE_ALGO_SEARCH_SUCCESS only if the frequency lock is successfully acquired. This behavior seems consistent with other demodulator drivers (e.g. stv090x, hd29l2, stv0900, stb0899, mb86a16). This patch has been successfully tested with DVB-T and DVB-T2 signals, on both PC and the mipsel STB running Enigma2. No apparent side effect has been observed on PC applications like Kaffeine. DVB-C is not available in my country so it's not tested.

2012-05-15[media] v4l2-event: fix regression with initial event handlingHans Verkuil
If the V4L2_EVENT_SUB_FL_SEND_INITIAL was set, then the application expects to receive an initial event of the initial value of the control. However, commit c53c2549333b340e2662dc64ec81323476b69a97 that added the new v4l2_subscribed_event_ops introduced a regression: while the code still queued that initial event the __v4l2_event_queue_fh() function was modified to ignore such requests if sev->elems was 0 (meaning that the event subscription wasn't finished yet). And sev->elems was only set to a non-zero value after the add operation returned. This patch fixes this by passing the elems value to the add function. Then the add function can set it before queuing the initial event.
