From ad62701720dd5d2a17c62f6c3bbd6ee629efcfaa Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Wed, 13 Sep 2017 16:37:50 -0300 Subject: [PATCH] [media] saa7146: make saa7146_use_ops const Make these const as they are not modified in the file referencing them. They are only used when their function pointer fields invokes a function and therefore none of the structure fields are getting modified. Also, add a const to the declaration in the header.
