Subject: [PATCH] usb: host: constify dev_pm_ops structures
Date: Sun, 15 Jan 2017 17:23:25 +0530 [thread overview]
Message-ID: <1484481205-27391-1-git-send-email-bhumirks@gmail.com> (raw)
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 powerpc
architecture.
