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:
