    Subject[PATCH 3/5] platform/chrome: cros_ec_debugfs: Set PROBE_PREFER_ASYNCHRONOUS
    Date
    This driver takes on the order of 40ms to start on some systems. It
    shouldn't have many cross-device dependencies to race with, nor racy
    access to shared state with other drivers, so this should be a
    relatively low risk change.

    This driver was pinpointed as part of a survey of top slowest initcalls
    (i.e., are built in, and probing synchronously) on a lab of ChromeOS
    systems.
