From 427da406bcaf4f51b561ed19de89f2401df85d05 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 22 Nov 2016 08:15:15 -0200 Subject: [media] vpdma: remove vpdma_enable_list_notify_irq() 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.
