From 729ce68c3e41dd92a5938410a282acce14e3f8c9 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 6 Aug 2017 04:25:15 -0400 Subject: media: exynos-gsc: 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 Reviewed-by: Sylwester Nawrocki Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/exynos-gsc/gsc-m2m.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/media/platform') diff --git a/drivers/media/platform/exynos-gsc/gsc-m2m.c b/drivers/media/platform/exynos-gsc/gsc-m2m.c index 33611a46ce35..2a2994ef15d5 100644 --- a/drivers/media/platform/exynos-gsc/gsc-m2m.c +++ b/drivers/media/platform/exynos-gsc/gsc-m2m.c @@ -747,7 +747,7 @@ static const struct v4l2_file_operations gsc_m2m_fops = { .mmap = gsc_m2m_mmap, }; -static struct v4l2_m2m_ops gsc_m2m_ops = { +static const struct v4l2_m2m_ops gsc_m2m_ops = { .device_run = gsc_m2m_device_run, .job_abort = gsc_m2m_job_abort, }; -- cgit v1.2.3
