of_find_node_by_path() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. This place doesn't do that, so fix it.

help
This option enables undefined behaviour sanity checker
Compile-time instrumentation is used to detect various undefined
behaviours in runtime. Various types of checks may be enabled
via boot parameter ubsan_handle
(see: Documentation/dev-tools/ubsan.rst).

default y
help
This option activates instrumentation for the entire kernel.
If you don't enable this option, you have to explicitly specify
UBSAN_SANITIZE := y for the files/directories you want to check for UB.
Enabling this option will get kernel image size increased
significantly.
config UBSAN_ALIGNMENT
bool "Enable checking of pointers alignment"
depends on UBSAN
default y if !HAVE_EFFICIENT_UNALIGNED_ACCESS
help
This option enables detection of unaligned memory accesses.
Enabling this option on architectures that support unaligned
accesses may produce a lot of false positives.
config TEST_UBSAN
tristate "Module for testing for undefined behavior detection"
depends on m && UBSAN
help
This is a test module for UBSAN.
It triggers various undefined behavior, and detect it.
