The call was removed by commit262303fe32("pciehp: fix wait command completion"). * <linux/interrupt.h> in pciehp_core.c Added by historic commit f308a2dfbe63 ("PCI: add PCI Express Port Bus Driver subsystem") to accommodate for a call to free_irq(): https://git.kernel.org/tglx/history/c/f308a2dfbe63 The call was removed by commit407f452b05("pciehp: remove unnecessary free_irq"). * <linux/time.h> in pciehp_core.c and pciehp_hpc.c Added by commit34d03419f0("PCIEHP: Add Electro Mechanical Interlock (EMI) support to the PCIE hotplug driver."), which was reverted by commitbd3d99c170("PCI: Remove untested Electromechanical Interlock (EMI) support in pciehp."). * <linux/module.h> in pciehp_ctrl.c, pciehp_hpc.c and pciehp_pci.c Added by historic commit c16b4b14d980 ("PCI Hotplug: Add SHPC and PCI Express hot-plug drivers"): https://git.kernel.org/tglx/history/c/c16b4b14d980 Module-related symbols were neither used back then in those files, nor are they used today. * <linux/slab.h> in pciehp_ctrl.c Added by commit5a0e3ad6af("include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h") to accommodate for calls to kmalloc(). The calls were removed by commit0e94916e60("PCI: pciehp: Handle events synchronously"). * "../pci.h" in pciehp_ctrl.c Added by historic commit 67f4660b72f2 ("PCI: ASPM patch for") to accommodate for usage of the global variable pcie_mch_quirk: https://git.kernel.org/tglx/history/c/67f4660b72f2 The global variable was removed by commit0ba379ec0f("PCI: Simplify hotplug mch quirk").

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.
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.
