    OMAPDSS: APPLY: make ovl_enable/disable synchronous · a3d0e4ae
    Tomi Valkeinen 提交于
    ovl->enable/disable are meant to be synchronous so that they can handle
    the configuration of fifo sizes. The current kernel doesn't configure
    fifo sizes yet, and so the code doesn't need to block to function (from
    omapdss driver's perspective).
    
    However, for the users of omapdss a non-blocking ovl->disable is
    confusing, because they don't know when the memory area is not used
    any more.
    
    Furthermore, when the fifo size configuration is added in the next merge
    window, the change from non-blocking to blocking could cause side
    effects to the users of omapdss. So by making the functions block
    already will keep them behaving in the same manner.
    
    And, while not the main purpose of this patch, this will also remove the
    compile warning:
    
    drivers/video/omap2/dss/apply.c:350: warning:
    'wait_pending_extra_info_updates' defined but not used
