ngene: properly handle __user ptr
commit 04da2daee383391954b34e7d0fe0281d75447d61 upstream.
Sparse is complaining about ngene's bad usage of a __user ptr:
>> drivers/media/pci/ngene/ngene-dvb.c:62:48: sparse: incorrect type in argument 2 (different address spaces)
drivers/media/pci/ngene/ngene-dvb.c:62:48: expected unsigned char const [usertype] *buf
drivers/media/pci/ngene/ngene-dvb.c:62:48: got char const [noderef] <asn:1>*buf
As this is intercepting a .write() file ops, we can't just memcpy. We need to use
copy_from_user.
