It's deprecated and only should be used by drivers which still use drm_platform_init, not by anyone else.
And indeed it's entirely unused and can be nuked.
This required a bit more fudging, but I guess kirin_dc_ops really wants to operate on the platform_device, not something else. Also bonus points for implementing abstraction, and then storing the vfunc in a global variable.
