    drm, kdb, kms: Add an enter argument to mode_set_base_atomic() API · 413d45d3
    Jason Wessel 提交于
    Some devices such as the radeon chips receive information from user
    space which needs to be saved when executing an atomic mode set
    operation, else the user space would have to be queried again for the
    information.
    
    This patch extends the mode_set_base_atomic() call to pass an argument
    to indicate if this is an entry or an exit from an atomic kernel mode
    set change.  Individual drm drivers can properly save and restore
    state accordingly.
