(Maybe checkpatch complains? Ignore checkpatch). 2) Put a space between the git hash and the '('. 3) No blank line between the Fixes and the Reported-by. > -int wilc_debugfs_init(void) > +int wilc_debugfs_init(const struct file_operations *fops) You may as well make wilc_debugfs_init() void since no one checks it. > { > - int i; > - struct wilc_debugfs_info_t *info; > - > wilc_dir = debugfs_create_dir("wilc_wifi", NULL); > - for (i = 0; i < ARRAY_SIZE(debugfs_info); i++) { > - info = &debugfs_info[i]; > - debugfs_create_file(info->name, > - info->perm, > - wilc_dir, > - &info->data, > - &info->fops); > + if (IS_ERR_OR_NULL(wilc_dir)) { > + pr_err("Error creating debugfs\n"); > + return -EFAULT; > } Just check for NULL. If someone builds without debugfs enabled in their .config, that's their choice. No need to print a warning. regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
