Subject: Interpretation of sparse warning

The code sequence

        u32 macstat;
.....
        macstat = le32_to_cpu(rxhdr->mac_status);

generates the following sparse warnings

drivers/net/wireless/b43legacy/xmit.c:446:12: warning: cast to restricted type
drivers/net/wireless/b43legacy/xmit.c:446:12: warning: cast from restricted type

(#446 is the macstat = ..... line)

My version of sparse is from the git tree and was downloaded today.

I think the code sequence is correct. What, if anything, should I do to eliminate the warning?

Thanks,

Larry
