Subject: [PATCH] net: ibm: ibmveth: constify dev_pm_ops structures.
Date: Thu, 29 Jun 2017 11:14:50 +0530 [thread overview]
Message-ID: <24303710c4e099faa0ca7d9d92a71e53d6b66bcc.1498714986.git.arvind.yadav.cs@gmail.com> (raw)
dev_pm_ops are not supposed to change at runtime. All functions
working with dev_pm_ops provided by <linux/device.h> work with const
dev_pm_ops. So mark the non-const structs as const.
File size before:

15426 1256 0 16682 412a drivers/net/ethernet/ibm/ibmveth.o
File size After adding 'const':
text data bss dec hex filename
15618 1064 0 16682 412a drivers/net/ethernet/ibm/ibmveth.o
