The GuC log snapshot code would complain loudly if there was no GuC log to take a snapshot of or if the snapshot alloc failed. Originally, this code was only called on demand when a user (or developer) explicitly requested a dump of the log. Hence an error message was useful. However, it is now part of the general devcoredump file and is called for any GPU hang. Most people don't care about GuC logs and GPU hangs do not generally mean a kernel/GuC bug. More importantly, there are valid situations where there is no GuC log, e.g. SRIOV VFs. So drop the error message.

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 reStructuredText 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.
