From: Julia Lawall Date: Fri, 4 Aug 2017 12:09:45 +0000 (-0400) Subject: media: staging: media: atomisp: constify videobuf_queue_ops structures X-Git-Tag: v5.15~9827^2~750 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=38ffab3b52f8c93525c606a8609af4e47eb87644;p=platform%2Fkernel%2Flinux-starfive.git media: staging: media: atomisp: constify videobuf_queue_ops structures These videobuf_queue_ops structures are only passed as the second argument to videobuf_queue_vmalloc_init, which is declared as const. Thus the videobuf_queue_ops structures themselves can be const. Done with the help of Coccinelle. // @r disable optional_qualifier@ identifier i; position p; @@ static struct videobuf_queue_ops i@p = { ... }; @ok1@ identifier r.i; expression e1; position p; @@ videobuf_queue_vmalloc_init(e1,&i@p,...) @bad@ position p != {r.p,ok1.p}; identifier r.i; struct videobuf_queue_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct videobuf_queue_ops i = { ... }; // Signed-off-by: Julia Lawall Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab --- diff --git a/drivers/staging/media/atomisp/pci/atomisp2/atomisp_fops.c b/drivers/staging/media/atomisp/pci/atomisp2/atomisp_fops.c index c151c84..d8cfed3 100644 --- a/drivers/staging/media/atomisp/pci/atomisp2/atomisp_fops.c +++ b/drivers/staging/media/atomisp/pci/atomisp2/atomisp_fops.c @@ -643,14 +643,14 @@ static void atomisp_buf_release_output(struct videobuf_queue *vq, vb->state = VIDEOBUF_NEEDS_INIT; } -static struct videobuf_queue_ops videobuf_qops = { +static const struct videobuf_queue_ops videobuf_qops = { .buf_setup = atomisp_buf_setup, .buf_prepare = atomisp_buf_prepare, .buf_queue = atomisp_buf_queue, .buf_release = atomisp_buf_release, }; -static struct videobuf_queue_ops videobuf_qops_output = { +static const struct videobuf_queue_ops videobuf_qops_output = { .buf_setup = atomisp_buf_setup_output, .buf_prepare = atomisp_buf_prepare_output, .buf_queue = atomisp_buf_queue_output,
