From eb1ca9a428fdc3f98be4898f6cd8bcb803878619 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Mon, 1 Oct 2018 11:21:11 -0400 Subject: media: cx18: Don't check for address of video_dev Clang warns that the address of a pointer will always evaluated as true in a boolean context. drivers/media/pci/cx18/cx18-driver.c:1255:23: warning: address of 'cx->streams[i].video_dev' will always evaluate to 'true' [-Wpointer-bool-conversion] if (&cx->streams[i].video_dev) ~~ ~~~~~~~~~~~~~~~^~~~~~~~~ 1 warning generated. Check whether v4l2_dev is null, not the address, so that the statement doesn't fire all the time. This check has been present since 2009, introduced by commit 21a278b85d3c ("V4L/DVB (11619): cx18: Simplify the work handler for outgoing mailbox commands") Reported-by: Nick Desaulniers Signed-off-by: Nathan Chancellor Reviewed-by: Nick Desaulniers Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/pci/cx18/cx18-driver.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/media') diff --git a/drivers/media/pci/cx18/cx18-driver.c b/drivers/media/pci/cx18/cx18-driver.c index 56763c4ea1a7..a6ba4ca5aa91 100644 --- a/drivers/media/pci/cx18/cx18-driver.c +++ b/drivers/media/pci/cx18/cx18-driver.c @@ -1252,7 +1252,7 @@ static void cx18_cancel_out_work_orders(struct cx18 *cx) { int i; for (i = 0; i < CX18_MAX_STREAMS; i++) - if (&cx->streams[i].video_dev) + if (cx->streams[i].video_dev.v4l2_dev) cancel_work_sync(&cx->streams[i].out_work_order); } -- cgit v1.2.3
