From 1ea146a7dc9acbdbecadf9adc9eb2a75fa722a3f Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Sun, 15 Jan 2017 16:30:30 +0530 Subject: [PATCH] tty: serial: constify dev_pm_ops structures Declare dev_pm_ops structures as const as they are only stored in the pm field of a device_driver structure. This field is of type const, so dev_pm_ops structures having similar properties can be declared const too. Size details after cross compiling the .o file for blackfin architecture.
