Subject: [PATCH] drivers: remoteproc: constify rproc_ops structures
Date: Sat, 17 Dec 2016 16:59:36 +0530 [thread overview]
Message-ID: <1481974176-19912-1-git-send-email-bhumirks@gmail.com> (raw)
Declare rproc_ops structures as const as they are only passed as an
argument to the function rproc_alloc. This argument is of type const, so
rproc_ops structures having this property can be declared const too.
Done using Coccinelle:
@r1 disable optional_qualifier @
identifier i;
position p;
@@
static struct rproc_ops i at p = {...};
@ok1@
identifier r1.i;
position p;
@@
rproc_alloc(...,&i at p,...)
@bad@
position p!={r1.p,ok1.p};
identifier r1.i;

@depends on !bad disable optional_qualifier@
identifier r1.i;
