If anyone has any objections, please let me know. ------------------ From: Haotian Zhang commit c43bcd2b2aa3c2ca9d2433c3990ecbc2c47d10eb upstream. In cec_devnode_init(), the debugfs directory created with debugfs_create_dir() is not removed if bus_register() fails. This leaves a stale "cec" entry in debugfs and prevents proper module reloading. Fix this by removing the debugfs directory in the error path.
