[patch -resend] mmc: ushc: fix an endianness conversion in ushc_request()

[Dan Carpenter]

The ->cmd_idx field is 8 bits, not 16 so the call to cpu_to_le16()
will probably set cmd_idx to zero here on big endian systems.  My guess
is that this works because it has been tested on little endian systems
where the conversion to le16 is a nop.

I don't have a way to test this.

I have added a sentence to the changelog.  I have added David Vrabel to
the CC list.  This was originally sent to the mailing list on Mon, 21
Nov 2011 and there was no response.
