* to the SDIO glue layer only (e.g. sdio_mmc.c).
|
|
|
|
* 3. If a function needs protection, regardless of the CSR_WIFI_SINGLE_FUNCTION
|
|
|
|
* then we call directly the sdio_claim_host/sdio_release_host().

|
|
|
|
*
|
|
|
|
* Note: The _func and function pointers are _not_ the same.
|
|
|
|
* The former is the (struct sdio_func*) context, which restricts the use to the SDIO glue layer.
|
|
|
|
* The latter is the (CsrSdioFunction*) context, which allows calls from all layers.
