From b75ae07963f99f89319b17935af20513d57df577 Mon Sep 17 00:00:00 2001 From: Pavan Savoy Date: Thu, 24 Feb 2011 08:06:53 -0600 Subject: [PATCH] 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.
