Take the panel reference and put it back as required. drm_panel_add() and drm_panel_remove() add a panel to the global registry and removes a panel respectively. Use get() and put() helpers to keep up with refcounting. Signed-off-by: Anusha Srivatsa <redacted> --- drivers/gpu/drm/drm_panel.c | 2 ++ 1 file changed, 2 insertions(+)
