Jinjie Ruan 8cd08e3651 media: siano: Drop unnecessary error check for debugfs_create_dir/file() ... Both debugfs_create_dir() and debugfs_create_file() return ERR_PTR and never return NULL. As Hans suggested, this patch removes the error checking for both debugfs_create_dir() and debugfs_create_file() in smsdvb_debugfs_create(). This is because the DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in start_creating() which can handle it gracefully. So these checks are unnecessary. And as Hans pointed out, it's much better to first allocate debug_data before calling debugfs_create_dir, which need not to clean anything up in that case.
