Subject: [PATCH] backlight: pwm_bl: make of_device_ids const
Date: Tue, 20 Jun 2017 07:52:57 +0000 [thread overview]
Message-ID: <b9daeb15d40f6682803d8dafde3bc3dcb63909ff.1497940816.git.arvind.yadav.cs@gmail.com> (raw)
of_device_ids are not supposed to change at runtime. All functions
working with of_device_ids provided by <linux/of.h> work with const
of_device_ids. So mark the non-const structs as const.
