staging/android: remove driver_data from struct sync_fence_info

2016-02-08T01:34:58Z

It is unclear in what situations driver_data should be used thus better do not upstream it for now. If a need arises in the future a discussion can be started to re-add it. Signed-off-by: Gustavo Padovan Signed-off-by: Greg Kroah-Hartman

staging/android: remove SYNC_WAIT ioctl

2016-02-08T01:34:58Z

This ioctl is replicating the work of poll() syscall so let's take the opportunity that this is still on staging tree and remove the duplication and force new users to use the poll() standard interface. Signed-off-by: Gustavo Padovan Signed-off-by: Greg Kroah-Hartman

staging/android: remove sync_fence_create_dma()

2016-02-08T01:34:58Z

With the removal of struct sync_pt sync_fence_create_dma() now takes the same arguments as sync_fence_create() so let's keep only sync_fence_create(). Signed-off-by: Gustavo Padovan Reviewed-by: Maarten Lankhorst Signed-off-by: Greg Kroah-Hartman

staging/android: remove struct sync_pt

2016-02-08T01:34:58Z

struct sync_pt was just wrapping around struct fence and creating an extra abstraction layer. The only two members of struct sync_pt, child_list and active_list, were moved to struct fence in an earlier commit. After removing those two members struct sync_pt is nothing more than struct fence, so remove it all and use struct fence directly.

staging/android: rename 'sync_pt' to 'fence' in struct sync_fence_cb

2016-02-08T01:34:58Z

staging/android: rename sync_fence to sync_file

2016-02-08T01:34:58Z

sync_file has a more close meaning to what a sync_fence really, a struct that represent a file that can be used by userspace to get information on a fence, or wait for it to be signaled. Signed-off-by: Gustavo Padovan Reviewed-by: Maarten Lankhorst Signed-off-by: Greg Kroah-Hartman
