Nuno Sa 8bd8bfcdeb dev_printk: add new dev_err_probe() helpers 
[ Upstream commit dbbe7eaf0e ]

This is similar to dev_err_probe() but for cases where an ERR_PTR() or
ERR_CAST() is to be returned simplifying patterns like:

	dev_err_probe(dev, ret, ...);
	return ERR_PTR(ret)
or
	dev_err_probe(dev, PTR_ERR(ptr), ...);
	return ERR_CAST(ptr)

README 

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.
