staging: delete ti-st from staging
The 2 drivers originally staged, the core ti-st driver and the btwilink bluetooth driver have now moved to relevant directories, so deleting the ti-st/ from staging. Signed-off-by: Pavan Savoy <pavan_savoy@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
