There are two potential integer overflows in private_ioctl() if
userspace passes in a large sList.uItem / sNodeList.uItem. The
subsequent call to kmalloc() would allocate a small buffer, leading
to a memory corruption.

"param->u.wpa_associate.wpa_ie_len" comes from the user. We should
check it so that the copy_from_user() doesn't overflow the buffer.
Also further down in the function, we assume that if
"param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is
initialized. To make that work, I changed the test here to say that if
"wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return
-EINVAL.
Oddly, we only use the first element of the abyWPAIE[] array. So I
suspect there may be some other issues in this function.

Move functions managing the channel mapping to a new channel.c file, as done in
the staging VT6656 driver. The function names contained in card.c were prefixed
with CARD followed by the first letter of the return code, remove this and use
more coherent function names.
The following functions moved and were renamed:
ChannelValid -> is_channel_valid
CARDbSetChannel -> set_channel
CARDvInitChannelTable -> init_channel_table
CARDbyGetChannelMapping -> get_channel_mapping
CARDvSetCountryInfo -> set_country_info
CARDbySetSupportChannels -> set_support_channels
CARDbChannelGetList -> channel_get_list
CARDvSetCountryIE -> set_country_IE
CARDbGetChannelMapInfo -> get_channel_map_info
CARDvSetChannelMapInfo -> set_channel_map_info

Commit 902d241129 converted U32 to u32
which you would think would be just fine. Unfortunatly, it seems that
VIA only builds their code on a 32bit processor (which makes sense if
you think about it), but this doesn't work on x86-64. So fix up the few
places where this really wanted to be an unsigned long width.
