Since commit92a81562e6("leds: lp55xx: Add multicolor framework support to lp55xx") there are two subsequent tests if the chan_nr (reg property) is in valid range. One in the lp55xx_init_led() function and one in the lp55xx_parse_common_child() function that was added with the mentioned commit. There are two issues with that. First is in the lp55xx_parse_common_child() function where the reg property is tested right after it is read from the device tree. Test for the upper range is not correct though. Valid reg values are 0 to (max_channel - 1) so it should be >=. Second issue is that in case the parsed value is out of the range the probe just fails and no error message is shown as the code never reaches the second test that prints and error message. Remove the test form lp55xx_parse_common_child() function completely and keep the one in lp55xx_init_led() function to deal with it.

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.
