commit 1753c7c436 upstream.
When the pvrusb2 driver detects that there's something wrong with the
device, it prints a warning message. Right now those message are
printed in two different formats:
1. ***WARNING*** message here
2. WARNING: message here
There's an issue with the second format. Syzkaller recognizes it as a
message produced by a WARN_ON(), which is used to indicate a bug in the
kernel. However pvrusb2 prints those warnings to indicate an issue with
the device, not the bug in the kernel.
This patch changes the pvrusb2 driver to consistently use the first
warning message format. This will unblock syzkaller testing of this
driver.

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.
