DVB USB core refuses to load driver when current USB ID does not match IDs on driver table. Due to that dynamic IDs does not work. Replace reference design ID by dynamic ID in .probe() in order to get it working. Signed-off-by:

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. Signed-off-by:Santosh Nayak <santoshprasadnayak@gmail.com> Signed-off-by:

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. Signed-off-by:

Enable the LNA amplifier also for DVB-T (like for DVB-T2 and DVB-C); this greatly improves reception of weak signals without affecting the reception of the strong ones. Experimental data (collected with the mipsel STB) on the weakest frequencies available in my area: LNA OFF: MUX level BER picture RAI mux 4 72% 32000 corrupted TIMB 2 75% 14 OK TVA Vicenza 68% 32000 corrupted RAI mux 2 78% 14 OK LNA ON: MUX level BER picture RAI mux 4 73% 1500 OK TIMB 2 76% 0 OK TVA Vicenza 69% 0 OK RAI mux 2 79% 0 OK Moreover, with LNA enabled, the PCTV 290e was able to pick up 2 new frequencies matching the integrated tuner of my Panasonic G20 TV, which is really good.

As reported by Masanari, this macro is using "KERN_ERR" instead of "KERN_ERROR". That would lead into a compilation breakage, if this macro were used somewhere inside the driver. Instead of fixing the macro, as originally proposed, let's just remove the dead code. Reported-by:

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 c53c2549 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. Signed-off-by:

For the ov7670 camera to return images at the requested frame rate, it needs to make calculations based on the clock speed, which is a completely external factor (depends on the wiring of the system). On the XO-1.5, which is the only known via-camera user, the camera is clocked at 90MHz. Pass this information to the ov7670 driver, to fix an issue where a framerate of 3x the requested amount was being provided. Signed-off-by:

This flag is for legacy drivers only and will go away in the future. A note regarding commit 5126f259 (v4l2-dev: add flag to have the core lock all file operations): That commit message suggests that by not taking the core lock for fops other than unlocked_ioctl all problems relating to AB-BA locking and mm->mmap_sem are solved. This is not the case. More work needs to be done by moving the core lock further down into video_ioctl2. It should only be taken after the copy_from/to_user calls are done. Signed-off-by:
