Hi Adrian
My concern that ufs_debugfs_init() is called in module_init(), but your
another debugfs initialization function ufs_debugfs_hba_init(hba)
called in the UFS host probe path. 

If these two (module_init() and module_platform_driver())
initializaiton sequence always as your expectation: ufs_debugfs_init()-
->ufs_debugfs_hba_init(), that is fine, otherwise, it is better just
group them, make it simpler.


Thanks,
