The Intel SPI controller does not support low level operations, like reading the flag status register (FSR). It only exposes a set of high level operations for software to use. For this reason check the return value of micron_st_nor_read_fsr() and if the operation was not supported, use the status register value only. This allows the chip to work even when attached to Intel SPI controller (there are such systems out there).

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.
