    drm/i915: Use fb->pitches[0] in cursor code · 1e1bb871
    Ville Syrjälä authored
    The cursor code currently ignores fb->pitches[0] (except when creating
    the fb itself), and just uses the cursor_width*4 as the stride. Let's
    make sure fb->pitches[0] actually matches what we expect it to be.
    
    We can also relax the stride vs. cursor width relationship on 845/865
    since the stride is programmed separately. The only constraint is that
    width*cpp doesn't exceed the stride, and that's already been checked
    by the core since it makes sure the entire plane fits within the fb.
    
    We can also drop the bo size check as that's already checked when
    we create the fb. That is the fb is guaranteed to fit within the bo.
    
    v2: Rebase due to i845_cursor_ctl() and i9xx_cursor_ctl()
