Compiling vtunerc module on kernel 4.9.0.9

Hi,

I am trying to use the vtunerc.ko module with kernel 4.9.0.9.

I successfully compiled and installed the module, but when I start the satip client it crashes with this dmesg. I suspect some patches are needed for this kernel. Could you help please? Thanks.

I suspect there is something wrong with the vtunerc_ctrldev_ioctl function in vtunerc_ctrldev.c

Please help me, it's a pity we can't use this module on recent Linux distributions.
