commit2cbd27267fupstream. Apply only valid chip select value. This change fixes case where chip select is set to initial value of '-1' during probe and PM supend and subsequent resume can try to use the value with undefined behaviour. Also in case where gpio based chip select, the check in bcm_qspi_chip_select() shall prevent undefined behaviour on resume.

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.
