Subject: media: staging: media: atomisp: constify videobuf_queue_ops structures
Author: Julia Lawall <julia.law...@lip6.fr>
Date: Fri Aug 4 08:09:45 2017 -0400
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.
