mount_crypt_stat is assigned to &ecryptfs_superblock_to_private(ecryptfs_dentry->d_sb)->mount_crypt_stat, and mount_crypt_stat is not the first object in struct ecryptfs_sb_info. mount_crypt_stat is therefore never NULL. At the same time, no crash in ecryptfs_lookup() has been reported, and the lookup functions in other file systems don't check if d_sb is NULL either. Given that, remove the NULL check. Signed-off-by:
