platform/chrome: cros_ec_lightbar: Reduce ligthbar get version command
[ Upstream commit 1e7913f ] By default, the lightbar commands are set to the biggest lightbar command and response. That length is greater than 128 bytes and may not work on all machines. But all EC are probed for lightbar by sending a get version request. Set that request size precisely. Before the command would be: cros_ec_cmd: version: 0, command: EC_CMD_LIGHTBAR_CMD, outsize: 194, insize: 128, result: 0 Afer: cros_ec_cmd: version: 0, command: EC_CMD_LIGHTBAR_CMD, outsize: 1, insize: 8, result: 0 Fixes: a841178 ("mfd: cros_ec: Use a zero-length array for command data") Signed-off-by: Gwendal Grignou <gwendal@chromium.org> Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
