From eb5c79828cfa72e8dbdf2db842a781ad6806cdaf Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Sat, 25 Jan 2025 20:32:15 +0100 Subject: [PATCH] firmware: cs_dsp: FW_CS_DSP_KUNIT_TEST should not select REGMAP Enabling a (modular) test should not silently enable additional kernel functionality, as that may increase the attack vector of a product. Fix this by making FW_CS_DSP_KUNIT_TEST (and FW_CS_DSP_KUNIT_TEST_UTILS) depend on REGMAP instead of selecting it. After this, one can safely enable CONFIG_KUNIT_ALL_TESTS=m to build modules for all appropriate tests for ones system, without pulling in extra unwanted functionality, while still allowing a tester to manually enable REGMAP_BUILD and this test suite on a system where REGMAP is not enabled by default.
