commit969b276718upstream. In case of overlaid regions in which their biggest erase size command overpasses in size the region's size, only the non-overlaid portion of the sector gets erased. For example, if a Sector Erase command is applied to a 256-kB range that is overlaid by 4-kB sectors, the overlaid 4-kB sectors are not affected by the erase. For overlaid regions, 'region->size' is assigned to 'cmd->size' later in spi_nor_init_erase_cmd(), so 'erase->size' can be greater than 'len'.

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.
