This means we also need to slightly restructure the exit code, so that final cleanup of the drm_device is triggered by unregistering the platform device. Note that devres is both clean up when the driver is unbound (not the case for vkms, we don't bind), and also when unregistering the device (very much the case for vkms). Therefore we can rely on devres even though vkms isn't a proper platform device driver. This also somewhat untangles the load code, since the drm and platform device setup are no longer interleaved, but two distinct steps. v2: use devres_open/release_group so we can use devm without real hacks in the driver core or having to create an entire fake bus for testing drivers. Might want to extract this into helpers eventually, maybe as a mock_drm_dev_alloc or test_drm_dev_alloc. v3: Only deref vkms_device after checking it (Melissa) Reviewed-by: Melissa Wen <melissa.srw@gmail.com> Cc: Melissa Wen <melissa.srw@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Cc: Haneen Mohammed <hamohammed.sa@gmail.com> Cc: Daniel Vetter <daniel@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20200909091833.440548-1-daniel.vetter@ffwll.ch |
