Subject: [PATCH 1/6] lib: math: Move kunit tests into tests/ subdir
From: Luis Felipe Hernandez <luis.hernandez093@...il.com>
This patch is a follow-up task from a discussion stemming from point 3
in a recent patch introducing the int_pow kunit test [1] and
documentation regarding kunit test style and nomenclature [2].
Colocate all kunit test suites in lib/math/tests/ and
follow recommended naming convention for files <suite>_kunit.c
and kconfig entries CONFIG_<name>_KUNIT_TEST.
