 This feature is useful when you want to post the coredump as soon as possible after a crash and it is not desirable to wait for the next periodic upload set by :kconfig:option:`CONFIG_MEMFAULT_HTTP_PERIODIC_UPLOAD_INTERVAL_SECS`.
 Alternatively, you can manually trigger the coredump upload by calling the function :c:func:`memfault_zephyr_port_post_data`.
-The :c:function:`memfault_coredump_has_valid_coredump` function can be used to check if a coredump is available.
