Grygorii Strashko f696186203 net: ethernet: ti: cpsw: fix NULL pointer dereference in switch mode
In switch mode on struct cpsw_slave->ndev field will be initialized with
proper value only for the one cpsw slave port, as result
cpsw_get_usage_count() will generate "Unable to handle kernel NULL pointer
dereference" exception when first ethernet interface is opening
cpsw_ndo_open(). This issue causes boot regression on AM335x EVM and
reproducible on am57xx-evm (switch mode).
Fix it by adding additional check for !cpsw->slaves[i].ndev in
cpsw_get_usage_count().

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
