txgbe_shutdown() relies on txgbe_dev_shutdown() to initialise wake by passing it by reference. However, txgbe_dev_shutdown() doesn't use this parameter at all. wake is then passed uninitialised by txgbe_dev_shutdown() to pci_wake_from_d3(). Resolve this problem by: * Removing the unused parameter from txgbe_dev_shutdown() * Removing the uninitialised variable wake from txgbe_dev_shutdown() * Passing false to pci_wake_from_d3() - this assumes that although uninitialised wake was in practice false (0). I'm not sure that this counts as a bug, as I'm not sure that it manifests in any unwanted behaviour. But in any case, the issue was introduced by: 3ce7547e5b71 ("net: txgbe: Add build support for txgbe") Flagged by Smatch as: .../txgbe_main.c:486 txgbe_shutdown() error: uninitialized symbol 'wake'. No functional change intended. Compile tested only.

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.
