-TODO:
-- support more USB card reader of Realtek family
-- use kernel coding style
-- checkpatch.pl fixes
-- stop having thousands of lines of code duplicated with staging/rts_pstor
-- This driver contains an entire SD/MMC stack -- it should use the stack in
- drivers/mmc instead, as a host driver e.g. drivers/mmc/host/realtek-usb.c;
- see drivers/mmc/host/ushc.c as an example.
-- This driver presents cards as SCSI devices, but they should be MMC devices.
