Hi !
Recently I found that that sparse by default doesn't endianness
checks. So I changed my compilation habit to be
make modules C=1 SUBDIRS=drivers/net/wireless/libertas CHECKFLAGS="-D__CHECK_ENDIAN__"
so that I get the little-endian checks from sparse as well. That
showed up a good bunch of problems. The following RFC patch is
against libertas-2.6. I hope that all fixes are correct.

I now only have a few sparse warnings related to get_unaligned() or a weird
casting in if_sdio.c.

You can remove the line immediately. gpio->header.len _should_ be
__le16 already (from types.h) so therefore we don't need this bit at
all.
Rest of the stuff looks great though.
