Patryk Duda b6fc20e9bd platform/chrome: cros_ec_proto: Lock device when updating MKBP version ... commit df615907f1bf907260af01ccb904d0e9304b5278 upstream. The cros_ec_get_host_command_version_mask() function requires that the caller must have ec_dev->lock mutex before calling it. This requirement was not met and as a result it was possible that two commands were sent to the device at the same time. The problem was observed while using UART backend which doesn't use any additional locks, unlike SPI backend which locks the controller until response is received.
