If the attention button is pressed to power on the slot AND the user powers on the slot via sysfs before 5 seconds have elapsed AND powering on the slot fails because either the slot is unoccupied OR the latch is open, we neglect turning off the green LED so it keeps on blinking. That's because the error path of pciehp_sysfs_enable_slot() doesn't call pciehp_green_led_off(), unlike pciehp_power_thread() which does. The bug has been present since 2004 when the driver was introduced. Fix by deduplicating common code in pciehp_sysfs_enable_slot() and pciehp_power_thread() into a wrapper function pciehp_enable_slot() and renaming the existing function to __pciehp_enable_slot(). Same for pciehp_disable_slot(). This will also simplify the upcoming rework of pciehp's event handling.

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.
