/**
 * struct firmware_fallback_config - firmware fallback configuration settings
 *
 * Helps describe and fine tune the fallback mechanism.
 *
 * @force_sysfs_fallback: force the sysfs fallback mechanism to be used
 *      as if one had enabled CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y.
 *      Useful to help debug a CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y
 *      functionality on a kernel where that config entry has been disabled.
 * @ignore_sysfs_fallback: force to disable the sysfs fallback mechanism.
 *      This emulates the behaviour as if we had set the kernel
 *      config CONFIG_FW_LOADER_USER_HELPER=n.
 * @old_timeout: for internal use
 * @loading_timeout: the timeout to wait for the fallback mechanism before
 *      giving up, in seconds.
