Messages in this thread Patch in this message | | | From | Julia Lawall <> | Subject | [PATCH 12/12] power: reset: account for const type of of_device_id.data | Date | Tue, 2 Jan 2018 14:28:08 +0100 |
| |
This driver creates a const structure 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.
