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. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
