mtd: spi-nor: Clear WEL bit when erase or program errors occur
When an Erase or Program error occurs on a spansion/cypress or a
micron flash, the WEL bit remains set to one and should be cleared
with a WRDI command in order to protect against inadvertent writes
that can possible corrupt the contents of the memory.

Winbond, macronix, gd, etc., do not support the E_ERR and P_ERR bits in the
Status Register and always clear the WEL bit regardless of the outcome
of the erase or page program operation (ex w25q40bw, MX25L25635E).

Issue a WRDI command when erase or page program errors occur.

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.
