Uwe Kleine-König efd8e6d19c PCI: exynos: Don't discard .remove() callback
commit 83a939f0fdc208ff3639dd3d42ac9b3c35607fd2 upstream.

With CONFIG_PCI_EXYNOS=y and exynos_pcie_remove() marked with __exit, the
function is discarded from the driver. In this case a bound device can
still get unbound, e.g via sysfs. Then no cleanup code is run resulting in
resource leaks or worse.

The right thing to do is do always have the remove callback available.
This fixes the following warning by modpost:

  WARNING: modpost: drivers/pci/controller/dwc/pci-exynos: section mismatch in reference: exynos_pcie_driver+0x8 (section: .data) -> exynos_pcie_remove (section: .exit.text)

(with ARCH=x86_64 W=1 allmodconfig).

Fixes: 340cba6092 ("pci: Add PCIe driver for Samsung Exynos")

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.
