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.

EC returns EC_RES_IN_PROGRESS if the host command needs more time to complete. Whenever receives the return code, cros_ec_send_command() sends EC_CMD_GET_COMMS_STATUS to query the command status. Separate cros_ec_wait_until_complete() from cros_ec_send_command(). It sends EC_CMD_GET_COMMS_STATUS and waits until the previous command was completed, or encountered error, or timed out.

The last resume result exposing logic in cros_ec_sleep_event() incorrectly requires S0ix support, which doesn't work on ARM based systems where S0ix doesn't exist. That's because cros_ec_sleep_event() only reports the last resume result when the EC indicates the last sleep event was an S0ix resume. On ARM systems, the last sleep event is always S3 resume, but the EC can still detect sleep hang events in case some other part of the AP is blocking sleep. Always expose the last resume result if the EC supports it so that this works on all devices regardless of S0ix support. This fixes sleep hang detection on ARM based chromebooks like Trogdor.

Add Kunit tests for returning 0 from send_command() in cros_ec_get_host_command_version_mask(). Note that because the 2 cros_ec_get_host_command_version_mask() use the same `ver_mask`. cros_ec_proto_test_query_all_no_host_sleep_return0() polluates the `ver_mask` and returns 0 on the second send_command() to make sure the second cros_ec_get_host_command_version_mask() doesn't take the garbage from the previous call.

cros_ec_query_all() uses cros_ec_get_host_command_version_mask() to query the supported MKBP version; cros_ec_get_host_command_version_mask() uses send_command() for transferring the host command. Returning >=0 from send_command() only denotes the transfer was success. cros_ec_get_host_command_version_mask() should check if EC wasn't happy by checking `msg->result`. Add a Kunit test for returning error in `msg->result` in cros_ec_get_host_command_version_mask(). For the case, cros_ec_query_all() should find the EC device doesn't support MKBP. Reviewed-by:
