Zhang Rui dd64ea0337 thermal: intel: int340x: processor: Fix warning during module unload [ Upstream commit `99ca0b57e4` ] The processor_thermal driver uses pcim_device_enable() to enable a PCI device, which means the device will be automatically disabled on driver detach. Thus there is no need to call pci_disable_device() again on it. With recent PCI device resource management improvements, e.g. commit `f748a07a0b` ("PCI: Remove legacy pcim_release()"), this problem is exposed and triggers the warining below. [ 224.010735] proc_thermal_pci 0000:00:04.0: disabling already-disabled device [ 224.010747] WARNING: CPU: 8 PID: 4442 at drivers/pci/pci.c:2250 pci_disable_device+0xe5/0x100 ...

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.
