Well, as far as I am concerned, the adv7511_exit() in the same file has already dealt with the issue. Therefore, it might not be necessary to add another mipi_dsi_driver_unregister().
The issue is that adv7511_exit() is not called if adv7511_init() fails.
Sorry, I can not find the caller of adv7511_init(). Please give me more detail.
It's called by the kernel when the module is unloaded (module_exit). It's not what Laurent is saying though.
His point is that in adv7511, if i2c_add_driver fails, you'll still need to call mipi_dsi_driver_unregister to clean things up.
