Manuel Ullmann 1809c30b6e net: atlantic: always deep reset on pm op, fixing up my null deref regression 
The impact of this regression is the same for resume that I saw on
thaw: the kernel hangs and nothing except SysRq rebooting can be done.

Fixes regression in commit cbe6c3a8f8 ("net: atlantic: invert deep
par in pm functions, preventing null derefs"), where I disabled deep
pm resets in suspend and resume, trying to make sense of the
atl_resume_common() deep parameter in the first place.

It turns out, that atlantic always has to deep reset on pm
operations. Even though I expected that and tested resume, I screwed
up by kexec-rebooting into an unpatched kernel, thus missing the
breakage.

This fixup obsoletes the deep parameter of atl_resume_common, but I
leave the cleanup for the maintainers to post to mainline.

Suspend and hibernation were successfully tested by the reporters.

Fixes: cbe6c3a8f8 ("net: atlantic: invert deep par in pm functions, preventing null derefs")

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.
