Staging tree fixes for 3.4-rc2

Browse Source 
Here are a number of bugfixes for the drivers/staging/ portion of the kernel
 that have been reported recently.
 Nothing major here, with maybe the exception of the ramster code can now be
 built so it is enabled in the build again, and lots of memory leaks that people
 like to have fixed on their systems.
