From 3faf93543ccb3410bfaf992a0de4a925631a3526 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Sun, 19 Feb 2017 15:07:53 +0530 Subject: pstore: constify pstore_zbackend structures The references of pstore_zbackend structures are stored into the pointer zbackend of type struct pstore_zbackend. The pointer zbackend can be made const as it is only dereferenced. After making this change the pstore_zbackend structures whose references are stored into the pointer zbackend can be made const too.
