From: Roger Tseng <rogerable@xxxxxxxxxxx>

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
3. Revise coding style and white spaces

v3:
1. Fix MMC detection fail when under xhci
2. Minor change of pm_runtime behavior in rtsx_usb_ms to prevent some rare
freeze due to erroneous Memstick card(not MS-Pro)
3. Further revise coding style as suggested in the thread of v2
4. Using managed resources: devm_*
5. Change license from "GPL v2 and later" to "GPL v2"

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