``esp_vfs_fat_sdmmc_unmount()`` is now deprecated, and you can use :cpp:func:`esp_vfs_fat_sdcard_unmount()` instead. This API is deprecated in previous ESP-IDF versions, but without a deprecation warning or migration guide. Since ESP-IDF v5.1, calling this ``esp_vfs_fat_sdmmc_unmount()`` API will generate a deprecation warning.
