Subject: [PATCH 1/2] powercap/drivers/dtpm: Constify powercap_zone_{,constraint_}ops
Date: Thu,  2 Dec 2021 15:37:33 +0100	[thread overview]
Message-ID: <20211202143734.101760-2-rikard.falkeborn@gmail.com> (raw)
In-Reply-To: <20211202143734.101760-1-rikard.falkeborn@gmail.com>

These are only passed as input to powercap_register_zone() which takes
pointers to const powercap_zone_ops and powercap_zone_constraint_ops.
Make them const to allow the compiler to put them in read-only memory.
