CE5.0 SD bus driver of SD V2.0 has memory leakage

The bug is found during the development of a CE5.0 device with SDIO Wifi in
the following folder:
C:\WINCE500\PUBLIC\COMMON\OAK\DRIVERS\SDCARD\SDBUS

Such that the SDIO Wifi is implemented to have SD card insert / removal
events for activiate / deactivate the Wifi.

Everytime SD card insert and removal events executed, the device lost 1.7KB
memory.

I believe the memory leak is in your SDHC driver,
or more likely within your wireless driver and
not SDBus itself. Does it happen if you try
something else, say SD Memory?

I make changes to the SD Bus driver.

And the problem solve, it is due to
1. CSDSlot::RemoveAllDevice() does not free up the CSDDevice object in
sdbus.cpp.
2. m_SDCardInfo.SDIOInformation.pFunctionInformation in sddevice.cpp does
not free up.
