platform/chrome: cros_kunit_util: add default value for `msg->result`

2022-07-21T08:49:28Z

Add default value for `msg->result` so that it won't be garbage bytes when the mock list is empty. Signed-off-by: Tzung-Bi Shih Reviewed-by: Guenter Roeck Link: https://lore.kernel.org/r/20220720044754.4026295-3-tzungbi@kernel.org

platform/chrome: merge Kunit utils and test cases

2022-07-21T08:49:28Z

Merge CROS_KUNIT and CROS_EC_PROTO_KUNIT_TEST so that when they're built as modules cros_kunit_util doesn't need to export the symbols. Signed-off-by: Tzung-Bi Shih Reviewed-by: Guenter Roeck Link: https://lore.kernel.org/r/20220720044754.4026295-2-tzungbi@kernel.org

platform/chrome: cros_kbd_led_backlight: fix build warning

2022-07-20T01:22:59Z

drivers/platform/chrome/cros_kbd_led_backlight.c got a new build warning when using the randconfig in [1]: >>> warning: unused variable 'keyboard_led_drvdata_ec_pwm' The warning happens when CONFIG_CROS_EC is set but CONFIG_OF is not set. Reproduce: - mkdir build_dir - wget [1] -O build_dir/.config - COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross W=1 \ O=build_dir ARCH=s390 SHELL=/bin/bash drivers/platform/chrome/ Fix the warning by using __maybe_unused. Also use IS_ENABLED() because CROS_EC is a tristate.
