Ye Bin 6810fad956 ext4: fix ext4_error_err save negative errno into superblock
Fix As write_mmp_block() so that it returns -EIO instead of 1, so that
the correct error gets saved into the superblock.

Cc: stable@kernel.org
Fixes: 54d3adbc29 ("ext4: save all error info in save_error_info() and drop ext4_set_errno()")

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
