Currently, for any multi-standard frontend it is assumed that it just has a single standard capability. This is fine in some cases, but makes things hard when there are incompatible standards in conjuction. Eg: DVB-S can be seen as a subset of DVB-S2, but the same doesn't hold the same for DSS. This is not specific to any driver as it is, but a generic issue. This was handled correctly in the multiproto tree, while such functionality is missing from the v5 API update. http://www.linuxtv.org/pipermail/vdr/2008-November/018417.html Later on a FE_CAN_2G_MODULATION was added as a hack to workaround this issue in the v5 API, but that hack is incapable of addressing the issue, as it can be used to simply distinguish between DVB-S and DVB-S2 alone, or another X vs X2 modulation. If there are more systems, then you have a potential issue. An application needs to query the device capabilities before requesting any operation from the device. Signed-off-by:

The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read. The semantic patch that makes this change is available in https://lkml.org/lkml/2011/11/25/107Signed-off-by:

There is a potential integer overflow in uvc_ioctl_ctrl_map(). When a large xmap->menu_count is passed from the userspace, the subsequent call to kmalloc() will allocate a buffer smaller than expected. map->menu_count and map->menu_info would later be used in a loop (e.g. in uvc_query_v4l2_ctrl), which leads to out-of-bound access. The patch checks the ioctl argument and returns -EINVAL for zero or too large values in xmap->menu_count. Signed-off-by:

GET_RES request support is mandatory for extension units, but some cameras still choke on it (one example is the Logitech QuickCam PTZ that returns a single byte for the PTZ relative control instead of four). Signed-off-by:

Instead of skipping the payload completely, which would make the resulting image corrupted anyway, store the payload normally and mark the buffer as erroneous. If the no_drop module parameter is set to 1 the buffer will then be passed to userspace, and tt will then be up to the application to decide what to do with the buffer. Signed-off-by:

Add mem, length and bytesused fields to the uvc_buffer structure and use them instead of accessing the uvc_buffer::buf m.offset, length and bytesused fields directly. This prepares the driver to the conversion to videobuf2. Signed-off-by:

Checking for &dev->int_in is useless because it returns the address of the embedded struct tm6000_endpoint, which will always be positive and therefore true. Signed-off-by:

The original patch used the fast USB quirk to enable fast access to registers in the tm6000_read_write_usb(). The applied patch moved the check to the tm6000_reset(), probably due to some merge conflicts. Signed-off-by:

Support add for IT9135 9005 devices With this patch IT9135 devices now move to using dvb-usb-it9135-01.fw firmware IT9137 remain on previous firmware. IT9135 devices seem more stable on this firmware. If the user wishes to remain on it9137 firmware they can change back using firmware=1 module option. Signed-off-by:

The msg->command field is 32 bits, and we should fill it with a call to cpu_to_le32(). The current code is broke on big endian systems. On little endian systems it truncates the 32 bit value to 16 bits which probably still works fine. Signed-off-by:

The DRX-K doesn't change the delivery system at set_properties, but do it at frontend init. This causes problems on programs like w_scan that, by default, opens both frontends. Instead, explicitly set the format when set_parameters callback is called. Tested-by:
