Date: Wed, 28 Jun 2017 11:12:00 +0530 From: Arvind Yadav <arvind.yadav.cs@...il.com> To: jsarha@...com, tomi.valkeinen@...com, airlied@...ux.ie Cc: dri-devel@...ts.freedesktop.org, linux-kernel@...r.kernel.org Subject: [PATCH v2] drm: tilcdc: tilcdc_tfp410: make of_device_ids const. 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.
