   2  * Stubs for some of the bottom edge functions.
   3  *
   4  * These stubs are optional functions in the bottom edge (SDIO driver
   5  * interface) API that not all platforms or SDIO drivers may support.
   6  *
   7  * They're declared as weak symbols so they can be overridden by
   8  * simply providing a non-weak declaration.
