From fdd488dffd598ef831a781446f8d56e68f0dcd37 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 6 Aug 2017 04:25:16 -0400 Subject: [PATCH] media: bdisp: 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 Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/sti/bdisp/bdisp-v4l2.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/platform/sti/bdisp/bdisp-v4l2.c b/drivers/media/platform/sti/bdisp/bdisp-v4l2.c index 7918b928f058..939da6da7644 100644 --- a/drivers/media/platform/sti/bdisp/bdisp-v4l2.c +++ b/drivers/media/platform/sti/bdisp/bdisp-v4l2.c @@ -360,7 +360,7 @@ out: bdisp_job_finish(ctx, VB2_BUF_STATE_ERROR); } -static struct v4l2_m2m_ops bdisp_m2m_ops = { +static const struct v4l2_m2m_ops bdisp_m2m_ops = { .device_run = bdisp_device_run, .job_abort = bdisp_job_abort, }; -- 2.11.0
