From 5c1401f83a16b7ee3762c9044ab56ed3f3cdcdcd Mon Sep 17 00:00:00 2001 From: Gustavo Padovan Date: Tue, 31 May 2016 16:58:57 -0300 Subject: [PATCH] staging/android: remove .{fence, timeline}_value_str() from timeline_ops Now that the value of fence and the timeline are not stored by sw_sync anymore we can remove this extra abstraction to retrieve this data. This patch changes both fence_ops (.fence_value_str and .timeline_value_str) to return the str directly. It also clean up struct sync_timeline_ops by removing both ops from there.
