Subject: [PATCH v6 0/4] Add modules for realtek USB card reader

From: Roger Tseng <rogerable@...ltek.com>

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"

v4:
1. Remove invocations to deprecated/removed mmc_suspend|resume_host APIs and
   unnecessary platform device pm routines
2. Support CRC-ignored R1 response for CMD13 in response to commit:
   a27fbf2f067b0cd6f172c8b696b9a44c58bfaa7a: mmc: add ignorance case for 
   CMD13 CRC error
3. Remove unnecessary #ifdef CONFIG_PM_RUNTIME

v5:
1. rtsx_usb_ms.c: adding header inclusion, removing unnecessary NULL checking,
   and add cancel_work_sync in removal handler to wait possible pending
   works.
(Changes only rtsx_usb_ms. Other files remain the same to v4)

v6:
NOTE:since the v3 of patch 1/3 (rtsx_usb) has been merged, only diffs are
submitted and splitted into two.
1. rtsx_usb.c: fix possible race conditions:
   rtsx_usb_bulk_transfer_sglist(): del_timer() => del_timer_sync()
   rtsx_usb_probe(): move setup_timer() before mfd_add_devices() and also
		     remove unnecessary init_timer()
2. rtsx_usb.c: rtsx_usb_suspend(): add comments to LED turn-off
(Changes only rtsx_usb.c. Other files remain the same to v5)

Roger Tseng (4):
  [v6 fix] mfd/rtsx_usb: fix possible race condition
  [v6 fix] mfd/rtsx_usb: add comment in rtsx_usb_suspend
  mmc: Add realtek USB sdmmc host driver
  memstick: Add realtek USB memstick host driver
