media: atomisp2: Array underflow in atomisp_enum_input()
The problem here is this code from atomisp_enum_input():
581 int index = input->index;
582
583 if (index >= isp->input_cnt)
584 return -EINVAL;
585
586 if (!isp->inputs[index].camera)
587 return -EINVAL;
"input->index" is a u32 which comes from the ioctl. We want negative
values of "index" to be counted as -EINVAL but they aren't. I've fixed
this by changing the type of "isp->input_cnt" to unsigned int.
