commit 2e3a7476ec3989e77270b9481e76e137824b17c0 upstream. Commitff67592cbd("mtd: spi-nor: Introduce spi_nor_set_mtd_info()") moved all initialization of the mtd fields at the end of spi_nor_scan(). Normally, the mtd info is only needed for the mtd ops on the device, with one exception: spi_nor_try_unlock_all(), which will also make use of the mtd->size parameter. With that commit, the size will always be zero because it is not initialized. Fix that by not using the size of the mtd_info struct, but use the size from struct spi_nor_flash_parameter.

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.
