From dd93e79c602c8219c0b69b0667601ed363b4191a Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Sat, 21 Jan 2017 07:45:31 -0200 Subject: [PATCH] [media] media: dvb-frontends: constify vb2_ops structure Declare vb2_ops structure as const as it is only stored in the ops field of a vb2_queue structure. This field is of type const, so vb2_ops structures having same properties can be made const too.
