The build fails with:
```console
module/evdi_fb.c: In function 'evdifb_create':
module/evdi_fb.c:427:21:
error: assignment discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
427 | info->fbops = efbdev->fb_ops;
| ^
````
A resolution is to treat discard-qualifiers warnings as non-error.
