When the platform initialization fails due to missing resources, it will return -EPROBE_DEFER after dsps_musb_init() has been called. dsps_musb_init() calls dsps_musb_dbg_init() to allocate the debugfs nodes. At a later point in time, the probe will be retried, and dsps_musb_dbg_init() will be called again. debugfs_create_dir() will fail this time, as the node already exists, and so the entire device probe will fail with -ENOMEM. Fix this by moving debugfs_remove_recursive() from dsps_remove() to the plaform's exit function, so it will be cleanly torn down when the probe fails. It also feels more natural this way, as .exit is the counterpart to .init. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
