In function dpcm_transport the compiler complains about ret not being used:
drivers/usb/storage/dpcm.c: In function `dpcm_transport':
drivers/usb/storage/dpcm.c:46: warning: unused variable `ret'
ret is not used if CONFIG_USB_STORAGE_SDDR09 is not set. Instead of adding
more ifdef's to the code this patch puts ret to use for the other 2 cases in
the switch statement (case 0 and default).

One message a day to report a particular bug is really enough.... :)
That said, I think it would be better to add the ifdef's instead of more
substantial code changes.

No problemo, I was just getting my feet wet on small compiler warning
fixes and the SubmitingPatches doc said ifdefs were from the devil. ;)
I'll sent a patch later sunday...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
FWIW, I prefer Bryan's patch instead of the #ifdefs.
