Felipe Balbi	a773d41927	tracing: Pass export pointer as argument to ->write() ... By passing an export descriptor to the write function, users don't need to keep a global static pointer and can rely on container_of() to fetch their own structure.

Chunyan Zhang	262e1f6e39	stm class: ftrace: Add ftrace-export-over-stm driver ... This patch adds a driver that models itself as an stm_source called stm_ftrace. Once the stm device and stm_ftrace have been linked via sysfs, the driver registers itself as a trace_export and everything passed to the interface from Ftrace subsystem will end up in the STM trace engine.
