Subject: [PATCH] misc: rtsx: Move Realtek Card Reader Driver to misc
From: rui_feng <rui_feng@...lsil.com.cn>
Move Realtek PCIE Card Reader Driver to misc.
1.Create a folder realtek to store rtl8411.c rts5209.c
rts5227.c rts5229.c rts5249.c rtsx_pcr.c rtsx_pcr.h.
2.Move include/linux/mfd/rtsx_common.h and include/linux/mfd/rtsx_pci.h
to include/linux.
3.Move all Kconfig and Makefile related to Realtek card readers to misc.
