With these kernel configs:
CONFIG_LEDS_CLASS=m
# CONFIG_LEDS_CLASS_MULTICOLOR is not set
CONFIG_LEDS_LP55XX_COMMON=y
CONFIG_LEDS_LP5521=m
CONFIG_LEDS_LP5562=m
leds-lp55xx-common.c has a build error because it is builtin and
calls an interface that is built as a loadable module (due to
LEDS_CLASS=m). By making LEDS_LP55XX_COMMON depend on LEDS_CLASS,
this config combination cannot happen, thus preventing the build error.
ld: drivers/leds/leds-lp55xx-common.o: in function `lp55xx_register_leds':
leds-lp55xx-common.c:(.text+0xc5f): undefined reference to `devm_led_classdev_register_ext'
Fixes: 33b3a561f4 ("leds: support new LP8501 device - another LP55xx common")

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.
