Márton Németh 9086c7b994 V4L/DVB (11573): uvcvideo: Prevent invormation loss with removing implicit casting 
The uvcvideo driver supports only one input, which is input 0. For all
other input index the return value shall be EINVAL. This patch fixes the
problem when the value 0x80000000 was incorrectly casted and treated as
a zero value.

The patch was tested with v4l-test 0.10 [2] with CNF7129 webcam found on
EeePC 901.

References:
[1] V4L2 API specification, revision 0.24

[2] v4l-test: Test environment for Video For Linux Two API
    http://v4l-test.sourceforge.net/

[Modified by Laurent Pinchart]

Invalid input value (u32)-1 would be accepted due to integer overflow. Make
sure the driver rejects it and returns -EINVAL.
