Commit33f45c44d6("mtd: Do not allow MTD devices with inconsistent erase properties") introduced a check to make sure ->erasesize and ->_erase values are consistent with the MTD_NO_ERASE flag. This patch did not take the 0 bytes partition case into account which can happen when the defined partition is outside the flash device memory range. Fix that by setting the partition erasesize to the parent erasesize.

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.
