Despite being exported, there's no prototype for it at the headers, as warned by sparse: Fixes this sparse warning: drivers/media/platform/ti-vpe/vpdma.c:1000:6: warning: no previous prototype for 'vpdma_enable_list_notify_irq' [-Wmissing-prototypes] void vpdma_enable_list_notify_irq(struct vpdma_data *vpdma, int irq_num, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ Worse than that, it is not even used, as making it static it would produce: drivers/media/platform/ti-vpe/vpdma.c:1000:13: warning: 'vpdma_enable_list_notify_irq' defined but not used [-Wunused-function] static void vpdma_enable_list_notify_irq(struct vpdma_data *vpdma, int irq_num, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ So, let's just get rid of the dead code. If needed in the future, someone could re-add it.
