I just broke the build :(
Note that the cleanup function is a bit confused: ade_data was never set as drvdata, and calling drm_crtc_cleanup directly is a bug - this
Yes, this is a bug. Thanks for pointing out this.
is called indirectly through drm_mode_config_cleanup, which calls into crtc->destroy, which already has the call to drm_crtc_cleanup. Which means we can just nuke it.
Aside: I have no idea why this driver depends upon ARM64. It doesn't build warning-free on 32bit, but otherwise it's perfectly fine.
Because this driver is written for ARM64 SoCs.
It makes compile-testing harder, the same reasons why depending upon specific arm platforms is really annoying (but lukily that problem seems to have stopped being one for the drm subsystem at least). Depending on CONFIG_OF and other stuff that's really needed is perfectly fine, but imo depending upon specific platforms and stuff really isn't. -Daniel
Thanks, -xinliang
