The usb_control_msg() can fail any time. Only continue writing sequence if there was no error with the previous write. If there was any problem stop sending URBs and propagate the error to the gspca_main. Signed-off-by: Márton NÃ

In driver ./drivers/media/video/usbvideo/quickcam_messenger.c in line 91: 91 usb_make_path(dev, cam->input_physname, sizeof(cam->input_physname)); After this line we use strncat: 92 strncat(cam->input_physname, "/input0", sizeof(cam->input_physname)); where sizeof(cam->input_physname) returns length of cam->input_phisname without length for null-symbol. But this parameter must be - "maximum numbers of bytes to copy", i.e.: sizeof(cam->input_physname)-strlen(cam->input_physname)-1. In this case, after call to usb_make_path the similar drivers use strlcat. Like in: drivers/hid/usbhid/hid-core.c: 1152 usb_make_path(dev, hid->phys, sizeof(hid->phys)); 1153 strlcat(hid->phys, "/input", sizeof(hid->phys)); Found by Linux Driver Verification Project. Use strlcat instead of strncat. Signed-off-by:

The videobuf_queue_ops function vector is not declared constant, but there's no need for the videobuf layer to ever change it. Make it const so that videobuf users can make their operations const without warnings. Signed-off-by:

On particularly weak signals, changing register 0xab after setting the interleave mode will cause the FEC lock to get lost (while still holding the EQ lock). So remove the write entirely, which seems to have had no adverse effect in either of my ClearQAM environments (and in particular resolves the customer's reported issue). Also flip around the order of the amhum optimization and the interleave setup to be consistent with the windows driver, which has the side-benefit of doing them both in the same call (since the amhum optimization can only be done once the interleave setup).

The HVR-1600 doesn't use the standard mechanism for computing the gain when in QAM mode, instead always forcing it to be 0x02. Provide the ability to override the algorithm on a per-board basis. This change results in an improvement of 0.4-0.6 dB for QAM tuning. This work was sponsored by ONELAN Limited. Cc: Steven Toth <stoth@kernellabs.com> Signed-off-by:

The sh51409 driver was only doing the QAM optimization a single time, and it would only occur if you received a lock instantaneously after the tuning request. Restructure the code so that the optimization occurs once you reach a signal lock. Note that this depends on the caller polling for status, but we don't have much choice at this point without an independent thread monitoring the lock status. Also, at this point pretty much every application polls for status lock after doing the tune, so the likelihood of the optimization not occurring in the real world is pretty low. The state machine has also been reworked such that setting the interleave mode is now a dependency of doing the QAM optimization. Before both were mutually exclusive, which was not consistent with the Windows driver. We now have a single state machine that controls both. The changes as-is are only enabled for the HVR-1600. Once the changes are tested with some of the other boards, this change should be made generic and the "_legacy" functions should be removed. This work was sponsored by ONELAN Limited. Signed-off-by:

Perform some optimization of the register configuration based on a trace of the HVR-1600 Windows i2c traffic (and consultation with Steven Toth). Note that some of these values may be able to be moved into the common driver, but I am holding off on that until they can be tested with other boards. This work was sponsored by ONELAN Limited.
