Bisection says this patch (28c47e16ea2a19adb47fe2c182cbd61cb854237c)
breaks kconfig stuff in v5.4-rc by creating circular
dependencies. Could someone send a -rc patch to fix this please?

	  The frame buffer device provides an abstraction for the graphics
	  hardware. It represents the frame buffer of some video hardware and
	  allows application software to access the graphics hardware through
	  a well-defined interface, so the software doesn't need to know
	  anything about the low-level (hardware register) stuff.
	  
	  Frame buffer devices work identically across the different
	  architectures supported by Linux and make the implementation of
	  application programs easier and more portable; at this point, an X
	  server exists which uses the frame buffer device exclusively.
	  On several non-X86 architectures, the frame buffer device is the
	  only way to use the graphics hardware.
	  
	  The device is accessed through special device nodes, usually located
	  in the /dev directory, i.e. /dev/fb*.
	  
	  You need an utility program called fbset to make full use of frame
	  buffer devices. Please read <file:Documentation/fb/framebuffer.rst>
	  and the Framebuffer-HOWTO at
	  <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
	  information.
	  
	  Say Y here and to the driver for your graphics board below if you
	  are compiling a kernel for a non-x86 architecture.
	  
	  If you are compiling for the x86 architecture, you can say Y if you
	  want to play with it, but it is not essential. Please note that
	  running graphical applications that directly touch the hardware
	  (e.g. an accelerated X server) and that are not frame buffer
	  device-aware may cause unexpected results. If unsure, say N.

	  This option enables support for the FAN control on the Mellanox
	  Ethernet and InfiniBand switches. The driver can be activated by the
	  platform device add call. Say Y to enable these. To compile this
	  driver as a module, choose 'M' here: the module will be called
	  mlxreg-fan.

...depends on HWMON (defined at drivers/hwmon/Kconfig:6), with definition...

menuconfig HWMON
	tristate "Hardware Monitoring support"
	default y
	depends on HAS_IOMEM
	help
	  Hardware monitoring devices let you monitor the hardware health
	  of a system. Most modern motherboards include such a device. It
	  can include temperature sensors, voltage sensors, fan speed
	  sensors and various additional features such as the ability to
	  control the speed of the fans. If you want this support you
	  should say Y here and also to the specific driver(s) for your
	  sensors chip(s) below.
	  
	  To find out which specific driver(s) you need, use the
	  sensors-detect script from the lm_sensors package.  Read
	  <file:Documentation/hwmon/userspace-tools.rst> for details.
	  
	  This support can also be built as a module. If so, the module
	  will be called hwmon.
