 816 * 3. If a function needs protection, regardless of the CSR_WIFI_SINGLE_FUNCTION
 817 *    then we call directly the sdio_claim_host/sdio_release_host().
 818 *    Use of this must be restricted to the SDIO glue layer only (e.g. sdio_mmc.c).
 819 *
 820 * Note: The _func and function pointers are _not_ the same.
 821 * The former is the (struct sdio_func*) context, which restricts the use to the SDIO glue layer.
 822 * The latter is the (CsrSdioFunction*) context, which allows calls from all layers.
