This patchset adds modules to support Realtek USB vendor specific class flash
card reader: one base module in MFD subsystem and two host modules in both mmc
and memstick subsystems. The architecture is similar to rtsx_pci.

This work is done primarily to replace the staging driver: staging/rts5139,
which doesn't utilize mmc nor memstick subsystems. Once the patchset or its
revision is applied, we may need Greg's help to remove the staging one.

v2:
1. Fix potential buffer overflow in rtsx_usb_seq_write_register()
2. Remove unnecessary casting and messages
2. Revise coding style and white spaces

Roger Tseng (3):
  mfd: Add realtek USB card reader driver
  mmc: Add realtek USB sdmmc host driver
  memstick: Add realtek USB memstick host driver
