mmc: sdio: Allow sdio operations in other threads during sdio_add_func()
This fixes a bug introduced by 807e8e40673d ("mmc: Fix sd/sdio/mmc initialization frequency retries") that prevented SDIO drivers from performing SDIO commands in their probe routines -- the above patch called mmc_claim_host() before sdio_add_func(), which causes a deadlock if an external SDIO driver calls sdio_claim_host(). Fix tested on an OLPC XO-1.75 with libertas on SDIO. Signed-off-by: Dmitry Shmidt <dimitrysh@google.com> Reviewed-and-Tested-by: Chris Ball <cjb@laptop.org> Signed-off-by: Chris Ball <cjb@laptop.org>
