From d7c3110c28dee67f6766ae26cac629358233a6b4 Mon Sep 17 00:00:00 2001 From: Gustavo Padovan Date: Thu, 28 Apr 2016 10:46:53 -0300 Subject: [PATCH] staging/android: remove name arg from sync_file_create() Simplifies the API to only receive the fence it needs to add to the sync and create a name for the sync_file based on the fence context and seqno.
