Drivers using the new IRQCHIP_PLATFORM_DRIVER_BEGIN helper
fail to link when compile-testing without CONFIG_OF,
as that means CONFIG_IRQCHIP is disabled as well:
ld.lld: error: undefined symbol: platform_irqchip_probe
>>> referenced by irq-meson-gpio.c
>>> irqchip/irq-meson-gpio.o:(meson_gpio_intc_driver) in archive drivers/built-in.a
>>> referenced by irq-mchp-eic.c
>>> irqchip/irq-mchp-eic.o:(mchp_eic_driver) in archive drivers/built-in.a
As the drivers are not actually used in this case, just
making the reference to this symbol conditional helps
avoid the link failure.
Fixes: f8410e6265 ("irqchip: Add IRQCHIP_PLATFORM_DRIVER_BEGIN/END and IRQCHIP_MATCH helper macros")

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.
