From 13e6bac82af018a0777d70626ae0119d889180e8 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 2 Jan 2018 14:28:07 +0100 Subject: [PATCH] iio: common: ssp_sensors: account for const type of of_device_id.data This driver creates a number of const structures that it stores in the data field of an of_device_id array. Add const to the declaration of the location that receives a value from the data field to ensure that the compiler will continue to check that the value is not modified and remove the const-dropping cast on the access to the data field. Done using Coccinelle.
