[PATCH v6] staging: greybus: Constify gb_audio_module_type
Posted by Ayush Tiwari 1 year, 10 months ago
Constify static struct kobj_type gb_audio_module_type to prevent
modification of data shared across many instances and to address the
checkpatch warning that "gb_audio_module_type" should be const. The
"gb_audio_module_type" struct is only used in one place:
err = kobject_init_and_add(&m->kobj, &gb_audio_module_type, NULL, ...
so checkpatch is correct that it can be made const.
