| From | Greg Kroah-Hartman <> | Subject | [PATCH v2 13/16] mcb: move to_mcb_device() to use container_of_const() | Date | Wed, 11 Jan 2023 12:30:15 +0100 |
| |
The driver core is changing to pass some pointers as const, so move to_mcb_device() to use container_of_const() to handle this change.
to_mcb_device() now properly keeps the const-ness of the pointer passed into it, while as before it could be lost.
