From 5003a83139be0d4226717ed1d960234516043c86 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 6 Aug 2017 04:25:14 -0400 Subject: [PATCH] media: vcodec: mediatek: constify v4l2_m2m_ops structures The v4l2_m2m_ops structures are only passed as the only argument to v4l2_m2m_init, which is declared as const. Thus the v4l2_m2m_ops structures themselves can be const. Done with the help of Coccinelle. // @r disable optional_qualifier@ identifier i; position p; @@ static struct v4l2_m2m_ops i@p = { ... }; @ok1@ identifier r.i; position p; @@ v4l2_m2m_init(&i@p) @bad@ position p != {r.p,ok1.p}; identifier r.i; struct v4l2_m2m_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct v4l2_m2m_ops i = { ... }; // Signed-off-by: Julia Lawall Acked-by: Rick Chang Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c b/drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c index f17a86b2f917..226f90886484 100644 --- a/drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c +++ b/drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c @@ -865,7 +865,7 @@ static void mtk_jpeg_job_abort(void *priv) { } -static struct v4l2_m2m_ops mtk_jpeg_m2m_ops = { +static const struct v4l2_m2m_ops mtk_jpeg_m2m_ops = { .device_run = mtk_jpeg_device_run, .job_ready = mtk_jpeg_job_ready, .job_abort = mtk_jpeg_job_abort,
