[PATCH] staging: rtl8712: changed struct members to __le32

[Jannik Becher]

Fixed sparse warning "cast to restricted __le32".
struct recv_stat and struct phy_stat have always little endian members.

Recent changes in the kernel source has turned on endian checking, which exposes 
a number of new Sparse warnings. If you plan on fixing more of them, please send 
the patches to me first. They should also be sent privately. That way I can test 
them on big-endian hardware. On LE hardware, the transformations all compile 
away and you cannot test if the patches break anything. If you do not plan to 
fix the other warnings, please let me know so that I can do it.

I have tested this patch and found it to be OK. My only complaint is that you 
should send the patch to Greg Kroah-Hartman <gregkh@linuxfoundation.org>. He 
handles changes to the staging tree.

Thanks,

Larry
