usbvision: fix crash on detecting device with invalid configuration

2016-04-20T06:40:46Z

commit fa52bd506f274b7619955917abfde355e3d19ffe upstream. The usbvision driver crashes when a specially crafted usb device with invalid number of interfaces or endpoints is detected. This fix adds checks that the device has proper configuration expected by the driver.

[media] usbvision-video: fix memory leak of alt_max_pkt_size

2013-06-21T14:29:24Z

1. usbvision->alt_max_pkt_size is not deallocated anywhere. 2. if allocation of usbvision->alt_max_pkt_size fails, there is no proper deallocation of already acquired resources. The patch adds kfree(usbvision->alt_max_pkt_size) to usbvision_release() as soon as other deallocations happen there. It calls usbvision_release() if allocation of usbvision->alt_max_pkt_size fails as soon as usbvision_release() is safe to work with incompletely initialized usbvision structure.

[media] v4l2: remove obsolete v4l2_chip_match_host()

2013-06-21T13:30:54Z

This function is no longer needed since it is now the responsibility of the v4l2 core to check if the DBG_G/S_REGISTER and DBG_G_CHIP_INFO ioctls are called for the bridge driver or not. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] usbvision: replace current_norm by g_std

2013-06-17T12:37:23Z

current_norm use is deprecated because it is per-devicenode and if you have more device nodes all dependent on the same video source, then this no longer works. Just implement g_std instead. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: add const to argument of write-only s_register ioctl

2013-03-24T11:47:01Z

This ioctl is defined as IOW, so pass the argument as const. Signed-off-by: Hans Verkuil Acked-by: Guennadi Liakhovetski Acked-by: Lad, Prabhakar Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: pass std by value to the write-only s_std ioctl

2013-03-24T09:47:00Z

This ioctl is defined as IOW, so pass the argument by value instead of by reference. I could have chosen to add const instead, but this is 1) easier to handle in drivers and 2) consistent with the s_std subdev operation.
