[PATCH 1/7] staging/android: remove doc from sw_sync

From: Gustavo Padovan
Date: Mon Jun 20 2016 - 12:10:08 EST


From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>

SW_SYNC should never be used by other pieces of the kernel apart from
sync_debug as it is only a Sync File Validation Framework, so hide any
info to avoid confuse this with a standard kernel internal API.
