Proposed patch to fix sg helper mistake

Please try the attached patch, which fixes a mistake in the sg helper conversion of drivers/mmc/card/queue.c.  I will test when I have an SD card handy...
Comment 3 Jens Axboe 2007-11-07 23:42:17 UTC 
Good work Roland, that would definitely explain data corruption. The patch is queued up here, going upstream later today.
Comment 4 Romano Giannetti 2007-11-08 01:12:32 UTC 
Tested. It works for me. (I am the original reporter).
Comment 5 Pierre Ossman 2007-11-10 02:34:52 UTC
