[BUG] Possible bug of missing error return code in __ext4_journalled_writepage()

[Jia-Ju Bai <baijiaju1990@xxxxxxxxx>]

In __ext4_journalled_writepage():
    ......
    inode_bh = ext4_journalled_write_inline_data(inode, len, page);
    if (inode_bh == NULL)
        goto out;
    ......
out:
    unlock_page(page);
out_no_pagelock:
    brelse(inode_bh);
    return ret;

When inode_bh is NULL, ret is not assigned with an error code like -ENOENT.
I wonder whether this is intentional? Or ret should be assigned with 
-ENOENT here?


Best wishes,
Jia-Ju Bai
