Kconfig treats the dependency as optional, but the header file only provides
normal declarations and no empty API stubs:
ld: fs/btrfs/extent_io.o: in function `writepage_delalloc':
extent_io.c:(.text+0x2b42): undefined reference to `__udivdi3'
ld: drivers/pmdomain/thead/th1520-pm-domains.o: in function `th1520_pd_power_off':
th1520-pm-domains.c:(.text+0x57): undefined reference to `th1520_aon_power_update'
ld: drivers/pmdomain/thead/th1520-pm-domains.o: in function `th1520_pd_power_on':
th1520-pm-domains.c:(.text+0x8a): undefined reference to `th1520_aon_power_update'
ld: drivers/pmdomain/thead/th1520-pm-domains.o: in function `th1520_pd_probe':
th1520-pm-domains.c:(.text+0xb8): undefined reference to `th1520_aon_init'
ld: th1520-pm-domains.c:(.text+0x1c6): undefined reference to `th1520_aon_power_update'
Since the firmware code can easily be enabled for compile testing, there
is no need to add stubs either, so just make it a hard dependency.

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 reStructuredText 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.
